Experience with dog breeding has taught geneticists ________. A) that, given enough time, any desired trait can be bred into dogs B) that purebred dogs have offspring with qualities identical to the parents, because all purebred dogs are alike genetically C) that, while physical traits can be molded through artificial selection, behavioral traits cannot D) that geographically isolated groups of dogs may be selected for quite different traits, resulting in a different dog breed
Answer:
D) that geographically isolated groups of dogs may be selected for quite different traits, resulting in a different dog breed
Explanation:
Artificial selection is a type of selective breeding made by humans in which offspring with desired traits are selected. Modern dogs evolved by artificial selection. Dog breeding began around 30,000 years ago from selective breeding of wolves that were separated from their original population and bred to produce dogs with desired traits (especially, loss of aggressive behavior). Purebred are reproductively isolated groups of dogs originated from the same lineage (i.e., the same common ancestor for each group), that never mated with another dog breed.
2) Micah and Taylor investigate the effect of tap water and spring water on the growth of plants.
They grew two plants of the same type and size in separate containers. Every three days, they
added the same amount of tap water to one plant and the same amount of spring water to the
other. Describe an action that would best improve the reliability of their results?
Answer:
To improve the reliability of the results, the nutritional component of each category of water must be tested and recorded.
Second, the experiment should be carried out under greenhouse conditions.
The above actions will afford more control. When an experiment is controlled, it means that except for the dependent variable, all other variables are kept constant by the scientist.
By performing the experiment under greenhouse conditions, the kind of water the plants receive, temperature and other biotic actors are kept within measurable limits thus increasing the reliability of the results.

You are tracking three loci in the fruit fly, loci A, B, and C, and want to know whether the loci are linked and if so what their physical distances are from one another as well as the physical order they are in. To find out this information you perform a three-point testcross with a fly that is heterozygous for all three alleles. The progeny of this cross are:

A/a B/b C/c 83
a/a B/b c/c 6
A/a b/b C/c 5
Total 1053
(a) What is the recombination frequency between loci A and B?
(b) What is the recombination frequency between loci B and C?
(c) What is the recombination frequency between loci A and C?
(d) Are these loci linked?
(e) Demonstrate the physical arrangement of the genes on the chromosome, i.e. the order of the genes on a chromosome as well as their map distances.
(f) Write out the genotypes of the parents for this cross, indicating which alleles are linked with one another for each parent?
Answer and Explanation:
The Crossing-over frequency between two genes depends on the distance between them. A short distance between genes is a very little target for crossing-over to occur, which means that only a few of them will happen, compared with the number of events between genes that are more separated between each other. Two genes that are very close will have a few recombination events and are strongly bounded. While two separated genes will have more chances of recombination and are not bound.
To know if two genes are linked, we must observe the progeny distribution. In a tri-hybrid cross, If individuals, whos genes assort independently, are test crossed, they produce a progeny with equal phenotypic frequencies 1:1:1:1:1:1:1:1. If we observe a different distribution, that is that phenotypes appear in different proportions, we can assume that genes are linked in the heterozygote parent.
In the present example, the phenotypic ratio shows different proportions than the expected ones if they were not linked.
We can recognize the parental gametes in the descendants because their phenotypes are the most frequent,
a/a B/b C/c 389
A/a b/b c/c 410
while the double recombinants are the less frequent.
a/a B/b c/c 6
A/a b/b C/c 5
And simple recombinant gametes produced by the cross, which frequencies are intermediate.
a/a b/b C/c 39
A/a B/b c/c 44
a/a b/b c/c 77
A/a B/b C/c 83
Comparing the parental and the double recombinant we will realize that they only change in the position of the alleles C/c. This suggests that the position of the gene C is in the middle of the other two genes, A and B, because in a double recombinant only the central gene changes position in the chromatid.
A------C------B
Now we will call Region I to the area between A and C and Region II to the area between C and B.
Once established the order of the genes we can calculate distances between them, and we will do it from the central gene to the genes on each side. First We will calculate the recombination frequencies, and we will do it by region. We will call P1 to the recombination frequency between A and C genes, and P2 to the recombination frequency between C and B.
P1 = (R + DR) / N
P2 = (R + DR)/ N
Where: R is the number of recombinants in each region, DR is the number of double recombinants in each region, and N is the total number of individuals. To calculate the recombination frequency, we have to know that 1% of recombinations = 1 map unit = 1cm. And that the maximum recombination frequency is always 50%.
So:
P1 = (R + DR) / N = 5 + 6 + 77 + 44 + 39 / 1053 = 171/1053 = 0.162 P2 = (R + DR)/ N = 6 + 5 + 83 / 1053 = 94/1053 = 0.089Now, to calculate the recombination frequency between the two extreme genes, A and B, we can just perform addition or a sum:
P1 + P2= Pt
0.162 + 0.089 = Pt
0.251 = Pt
The genetic distance will result from multiplying that frequency by 100 and expressing it in map units (MU). One centiMorgan (cM) equals one map unit (MU). The map unit is the distance between the pair of genes for which one of every 100 meiotic products results in a recombinant product.
P1 = 0.162 x 100 = 16.2%P2 = 0.089 x 100 = 8.9%Pt = 0.251 x 100 = 25.1 %(a) What is the recombination frequency between loci A and B? 0.251
(b) What is the recombination frequency between loci B and C? 0.089
(c) What is the recombination frequency between loci A and C? 0.162
(d) Are these loci linked? Yes. Their recombination frequency is inferior to 50% and the phenotypic rate is different from 1:1:1:1:1:1:1:1
(e) Demonstrate the physical arrangement of the genes on the chromosome, i.e. the order of the genes on a chromosome as well as their map distances.

What is the central idea of Food Safety Myths Exposed?
Classify the events according to the gas they primarily contribute to the atmosphere.
#1 goes to methane, #2 goes to oxygen,#3 goes to carbon dioxide,#4 goes to carbon dioxide. make sure you double check.
Explanation:
A plant can produce oxygen sufficient for the consumption of four people whereas carbon dioxide absorbed by the plant is more than forty-eight pounds. The total release of carbon dioxide by livestock is 15 % of the greenhouse gas production whereas methane production is 155-264 pounds. When a forest fire happens it releases a massive amount of carbon dioxide which is around 1.8 million tons.
What are greenhouse gases?Greenhouse gases are gases such as methane, carbon dioxide, CFCs, and HFCs. They have impacted the atmosphere negatively. The concentration of these gases is highly rising in the atmosphere at an alarming rate. These gases trap the heat of the sun and do not leak out.
Therefore, the emission of greenhouse gases should be monitored.

An organism that reproduces asexually will have
Answer:
An offspring identical to itself.
Explanation:
The difference between asexually reproduction and sexually reproduction is that when you asexually reproduce, you are simply duplicating yourself. There are many ways you can asexually reproduce, like after a certian growth time, you would just simply split yourself. A part of you can just come off too. The last one is franmentation. It is when you take a big part of you off, and then if it was big enough, it would grow. (Occurs in Starfish). But when you sexually reproduce, two haploids would come together, creating a diploid which would duplicate. And asexually reproduction, you would already start with a full set of genes. (Which is identical to your mother's)

1. The Hawaiian Islands are examples of islands that formed over a hotspot. Based on this information, which of the following processes formed the Hawaiian Islands? (2 points) Melted rock called magma rose through holes in Earth's crust and gradually solidified as it cooled. Tectonic movement forced certain segments of Earth's crust downward and other segments upward in jagged chunks. One tectonic plate moved beneath another plate at a subduction zone, causing the rock to melt and rise above Earth's surface. Segments of Earth's crust bent and doubled over, and moving wind and water gradually shaped the rock into gently sloping domes.
Answer:
The correct answer is - Melted rock called magma rose through holes in Earth's crust and gradually solidified as it cooled.
Explanation:
The Hawaiian Islands are the chain of eight major islands situated in U.S. of Hawaii. These are formed over a hot spot. About 75 million years ago such hotspot took place in the center of the Pacific Plate.
There are hot spot due to the volconic activity and in the moving over the tectonic plate of a subduction zone. Volcanic activity and overriding of plates that cause rising magma by melting the moving down plates whice leads to volcanic arcs formation. The magma that rose gradually cooled down and become solid over the time. It is an example of a large seamount and island chain created by hot-spot volcanism.
Thus, The correct answer is - Melted rock called magma rose through holes in Earth's crust and gradually solidified as it cooled.
