The opposable thumb is a trait that connects us to other primates; allowing us to grab and use tools and increasing chances for survival. This means it is a(n) __________.

Answers

Answer 1

Answer:

The options to this question are;

A. genotype

B. adaptation

C. selective pressure

D. stabilizing pressure

The answer is B) Adaptation

Explanation:

Adaptation is the process whereby an organism becomes well suited to survive in its natural environment, which is aided by the possession of certain traits called adaptive features. For example, the fins of a fish makes it fit to survive in an aquatic environment, likewise the opposable thumbs of humans make us well suited to survive in our environment.

As stated in the question, the opposable thumb i.e. movement of the thumb independently of the other four fingers, is a characteristics of primates. This unique feature (opposable thumb) allows us to grab things, get a good grasp of tools, use tools effectively, write things, etc. All these ability due to the possession of opposable thumb increases our chances of survival. Hence, the possession of opposable thumb is regarded as an ADAPTATION

Please write down prearation of perment slides of pollen grains by acetolysis method and study of different pollen characters: study of variation pattern in different taxa.

Answers

Answer is given below

Explanation:

Collection and preservation of pollen material: In clean glass pots containing 70% glacial acetic acid, some of the stamens are applied with clean forceps prior to flower synthesis and sometimes protected from diamonds or mature flower buds. Some polyologists recommend 70% ethyl alcohol to preserve feathers in place of glacial acetic acid. In this condition, pollen-filled feathers can be stored indefinitely.  The wings are transferred to a centrifuge tube and rinsed well with distilled water.the wings are crushed with a glass rod and the mixture is filtered through a cheesecloth or sieve. The lower part is recalled in the centrifuge tube.  A freshly prepared acetolysis mixture containing acetic anhydride and concentrated H2SO4 (sulfuric acid) in a ratio of 9: 1 is poured into a centrifuge tube containing the washed pollen. Care must be taken to connect the conceider. H2SO4 by acetic anhydride drop to prevent overheating. The acetolysis solution reacts violently with water. Glacial acetic acid washers are required to replace water with acetic acid, which does not react violently with the acetolysis solution. Although the acetolysis process varies from pathologist to pulmonologist, the following approach seems to be the most appropriate. From the first to the last acetic acid wash, care is taken regardless of the water solution. Only distilled water should be used for washing to prevent contamination.

Complete question:

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    389

A/a b/b c/c     410

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

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 = 0.089

Now, 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.  

A-------------------C-----------------B

A--- 16.2 UM --C ---8.9 UM--B

A-------------25.1 UM--------------B

Prophase:

The DNA supercoils and chromosomes condense, becoming visible under a microscope). The chromosomes are comprised of genetically identical sister chromatids, which are joined at a centromere). Paired centrosomes then move to the opposite poles of the cell and form microtubule spindle fibers , the nuclear membrane breaks down, and the nucleus dissolves .

Metaphase:

The microtubule spindle fibers from both centrosomes connect to the centromere of each chromosome , microtubule depolymerisation causes spindle fibers to shorten in length and contract , causing chromosomes to align along the center of the cell.

Anaphase:

The continued contraction of the spindle fibers cause genetically identical sister chromatids to separate . Once the chromatids separate, they are individual chromosomes. The genetically identical chromosomes move to the opposite poles of the cell .

Telophase:

Once the two chromosome sets arrive at the poles, spindle fibers dissolve  and chromosomes decondense, becoming invisible under light microscopes.  Nuclear membranes reform around each chromosome set , and cytokinesis occurs concurrently, splitting the cell into two separate cells.
