what is the key to the recognition of a trait whose expression is determined by the effects of two or more genes
Answer:
Explanation:
Polygenic inheritance occurs when many loci of a gene contributes to it genetic make up.
No particular allele can be selected for contributing to a particular traits all the allele are equally expressed.
Over expressitivity example is pleiotrophy effect have more than 5 fingers or toes
The offspring express more dominant traits that the normal mendelian principle
This signs indicate polygenic inheritance.

Explain to your lab mate the health risk associated with consuming a diet low in vitamin K along with the ingestion of antibiotics over multiple days. How would the termination of antibiotic treatment help to remove this health risk?
Answer:
Vitamin K, a fat soluble vitamin is rich in green leafy vegetables,and also produced by bacterial in the intestine.
Its major function is blood clotting or arrest of bleeding to prevent blood loss.
Antibiotics especially with Cephalosporins,reduces Vit. K absorption in the intestine. Intake of these antibiotic kill the targeted bacterial together with the the bacteria which produces Vit. K in the intestine.
Hence when antibiotic is taken with low level of Vit, K the individual is prone to excessive bleeding or haemorrhage,because the concentration of the vitamins is further depleted.
If the medication is stopped,the condition will improve because the bacteria which produces Vt K can resumes the secretions,and its absorption will resume
Explanation:
a) There are three nucleotide in each codon, and each of these nucleotides can have one of four different bases. How many possible unique codons are there?
b) If DNA had only two types of bases instead of four, how long would codons need to be to specify all 20 amino acids?
Answer:
Explanation:
There are 64 possible codons to be specified for, If we have three nucleotides with 4 bases the set of all combinations can encode
4x4x4 = 64 amino acids
This will give 64 different combinations of four nucleotides
If we have 2 bases with 4 nucleotide we have a possibility of having 16 codons specifying for 20 amino acid.
If we have 2 nucleotides with 4 bases the set of combination is
4×4 = 16 amino acids of four nucleotides

Why did the leaves rise? Will the leaf discs float faster or slower if the rate of photosynthesis is decreased? (5 points)
Answer:
Leave rise and floating depends on the production of oxygen.
Explanation:
The leaves rises due to consumption of oxygen which is produced during photosynthesis. Floating of leave occurs due to production of oxygen in the process of photosynthesis. The leaf discs float faster if the rate of photosynthesis is increases because oxygen production is also increases while the leaf discs float will be slower if the rate of photosynthesis is decreased due to low production of oxygen.

DIHYBRID CROSSES
In all of the examples we have only been concerned with one trait. It is possible, however, to track the inheritance of more than one trait at a time. When one is investigating the inheritance of two traits at once the cross is called a dihybrid cross. Strictly speaking, a dihybrid cross is one between two individuals that are heterozygous for two traits, meaning that they are hybrids in two senses. For example, in humans eye color is determined by multiple factors, but if we compare only blue eyes to brown eyes, brown is dominant (R) and blue acts as a recessive allele (r). If a man heterozygous for both eye color and bent little finger has a child with a woman who also heterozygous for both traits, this would be a dihybrid cross. Which is/are possible genotypes for a person with bent little finger and blue eyes?
1. bbrr
2. BBRR
3. BBrr
4. Bbrr
Referring to the previous question, which is/are possible genotypes for a person with straight little finger and blue eyes?
1. bbrr
2. BbRr
3. Bbrr
4. bbRr
Answer:
Question 1: bbrr
Question 2: bbRr
Explanation:
To address the first question, the possible genotype for someone with bent little finger and blue eyes would be bbrr.
Since brown eye (B) is dominant over blue eyes (b), in order for the blue eye color to be expressed, it has to be in bb condition. The only option with bb genotype is option 1.
For the second question, the possible genotype for a person with a straight little finger and blue eyes would be bbRr.
Blue eye genotype is bb as explained in the first question while straight little finger would be Rr since the bent little finger has been represented by the genotype rr in the first question.

Consider a material for a vascular graft application with proteins adsorbed to its surface and a second material with proteins covalently attached to its surface. For which material would you expect the protein layer to be more stable under flow conditions similar to those found in a blood vessel? Why?
Answer is given below :
Explanation:
Individual-specific proteins are placed on the graft material so that the body does not recognize the graft as a foreign substance and treats it as a part of the body’s natural tissue structure. If the body recognizes the graft as a foreign substance, it produces an immune response against it and leads to a graft rejection reaction by the body. In order for these proteins to attach to grafts, a covalent bond for absorption must be preferred. Absorption is a reversible process and, if used, can lead to de-absorption of bound proteins, including blood, after dissolving by turbulence and pulling to the grafting material by blood flow (velocity up to 40 cm/sec). The remaining infectious tissue is detected foreignly, activating the immune response. On the other hand, covalent bonding is irreversible in nature and vascular flow does not have a disruptive effect on the bond between the graft and the protein, reducing the stable state of the graft and the possibility of rejection.Which of the following best describes how crossing over occurs during meiosis?

somebody help me please A cross is performed between a bird that is homo for red feathers and a bird that is homo for blue feathers. Purple offspring result due to incomplete dominance. Then, two of the purple offspring are crossed. What proportion of the offspring from the second cross will be purple? 1 in 4 2 in 4 3 in 4 4 in 4
Answer:
2 in 4
Explanation:
Let PP are the gametes of red feather bird and pp are the gamete of blue feather bird. In the first cross they both will give purple feather bird because of incomplete dominance.
Consider Pp as the allele of purple offspring for the second cross. When two of the purple offspring are crossed, it will give the proportion of 2 in 4
F2: Pp X Pp
Offspring: PP, Pp,Pp, pp
So, only two offspring, Pp is with purple feathers while PP has red and pp has blue feathers.
Hence, the correct option is 2 in 4.
The proportion of the offspring from the second cross that would be purple will be 2 in 4.
Let us assume that the red feather color is controlled by allele A and that of blue feather color is controlled by allele B.
Homzygous red feather birds will have the genotype AA
Homzygous blue feather birds will have the genotype BB
Crossing the 2 birds:
AA x BB
AB AB AB AB
Thus, the purple offspring are AB.
Crossing 2 of the purple offspring:
AB x AB
AA AB AB BB
1 AA - red
2 AB - purple
1 BB - blue
Thus, 2/4 or 1/2 or 50% of the offspring from the second cross will be purple.

What energy yield (in molecules of ATPATP per molecule of monosaccharide) would you predict for the bacterial catabolism of raffinose, a trisaccharide
Answer:
The correct answer is 2.67 ATP per molecule.
Explanation:
With the help of sucrose, it comes to known that the dissociation of a sugar-sugar bond generates one phosphorylated monosaccharide. Therefore, raffinose, which is a trisaccharide exhibits bonds of two sugar-sugar molecules. Post dissociation, they will generate one regular monosaccharide and two phosphorylated monosaccharides.
There will be the generation of net ATPs by each phosphorylated monosaccharide as they are already phosphorylated. While the regular monosaccharide, which is first needed to get phosphorylated will only produce two ATPs. Thus, a total of 8 ATPs will be produced by one molecule of raffinose. After dividing by three monosaccharides, the molecule will produce 8/3 = 2.67 ATPs per monosaccharide.
Myristoyl-CoA is a saturated fatty acid with 14 carbons attached to coenzyme A. How many molecules of ATP would be generated from the complete oxidation of a single molecule of myristoyl-CoA
Answer:
Total ATP molecules produced = 94 molecules of ATP
Explanation:
Myristoyl-CoA, is a saturated fatty acid with 14 carbons which has been activated for oxidation by attachment to coenzyme A. When it has undergone complete oxidation, it will yield 7 acetyl-CoA molecules and 6 FADH₂ and 6 NADH molecules each.
Each of the 7 acetyl-CoA molecules obtained from its initial oxidation enters into the citric acid cycle and is completely oxidized to yield further ATP and FADH₂ and NADH molecules.
The overall yield of ATP from the various enzymatic steps is shown below:
Acyl-CoA dehydrodenase = 6 FADH₂
β-Hydroxyacyl-CoA dehydrogenase = 6 NADH
Isocitrate dehydrogenase = 7 NADH
α-Ketoglutarate dehydrogenase = 7 NADH
Succinyl-CoA synthase = 7 ATP (from substrate-level phosphorylation)
Succinate dehydrogenase = 7 FADH₂
Malate dehydrogenase = 7 NADH
Note: 1 FADH2 molecule yields 1.5 ATP; 1 NADH molecule yields 2.5 ATP molecules. Therefore,
Total ATP from FADH₂ molecules = 13 * 1.5 = 19.5
Total NADH molecules = 27 * 2.5 = 67.5
Total ATP molecules produced = 19.5 + 67.5 + 7 = 94
Total ATP molecules produced = 94 molecules of ATP
an advertisement on tv claims children grow faster with the use of vitamin gro. vitamin gro is a 25mg pill taken twice a day. the viewer has little knowledge about how children grow, but he knows that children need a complete diet and a good exercise routine. he decided to put the commercial to the test. the viewer uses his 6 nieces who are the same age to conduct the experiments. to make the experiment easier he uses his six nieces using labels such as child 1, child 2 and so on. he records their height every 3 days for 7 days. What are the variables?
Answer:
Independent variable - vitamin gro and exercise routine.
Dependent variable - growth of children or nieces.
Explanation:
There are two variables present in an experiment called dependent and independent variables.
Independent variables are those variables which can be controlled in an experiment and dependent variables are those variables which are measured in the experiment under the influence of the independent variable.
In the given experiment, the independent variable will be vitamin gro and exercise routine and the dependent variable is the growth of children or nieces because vitamin gro and exercise routine can be controlled and growth of children is dependent on vitamin gro and exercise routine.
