Which of the following comparisons of relative fitness for the M locus would most likely result in the fixation (frequency of 1 ) of the M allele after many generations of evolution. A. w(MM) = w(Mm) < w(mm) B. w(MM) < w(Mm) > w(mm) C. w(MM) = w(Mm) = w(mm) D. w(MM) > w(Mm) = w(mm)

There are two existing hypotheses for an unusually high frequency of a deleterious recessive allele in a certain population other than it is hidden in the heterozygous genotype and not exposed to selection.  Explain what these two likely hypotheses are and how you could distinguish between them based on your understanding of the applicable assumptions that are part of the Hardy-Weinberg Equilibrium Model

Evolution is driven by both nonrandom and random mechanisms. Identify the mechanisms of evolution that are random and comment on how they affect allele frequencies across generations.

The relative fitness values of three genotypes are wA/A =1.0, wA/a = 1.0, and wa/a = 0.7.a. If the population starts at the allele frequency p =0.5, what is the value of p in the next generation?b. What is the predicted equilibrium allele frequency ifthe rate of mutation of A to a is 2 × 10−5?

I believe that the correct answer is: p^2+2pq+q^2=1 I just want to make sure that I am understanding the Hardy-Weinberg Equilibrium correctly.

Imagine a locus with two alleles. Mutation at this locus changes one allele to the other (i.e. it does not create a new allele). If the rate of mutation from allele 1 to allele 2 is 0.00005 and the rate of mutation from allele 2 to allele 1 is 0.01, what is the equilibrium frequency of allele 2 (Give your answer to 5 decimal places)?

Imagine a population of 100 snails in which the shell colour is controlled by two alleles: B (black) and b (yellow) I) What is the total no. of loci for shell colour gene in this population II) in the snail population above, 20 out of the snails are yellow (bb) and 80 are black (BB or Bb). Of the 80 black snails, 30 are homozygous and 50 are heterozygous. How many loci for this gene are occupied by the B allele? III) What is the frequency of B allele? IV) Assuming that sexual reproduction takes place with random mating, no gene flow and no selection, what will be the frequency of yellow snails in next generation of the population described above? V) What will be the frequency of b allele in the next generation of the snail population described

Consider a set of genotypes with fitnesses: AA = 1.12 Aa = 1.04 aa = 1.0 Where the frequency of the "A" allele is 0.4. A. What is delta p, the change in the allele frequency to the next generation?  B. What is the new frequency of the "A" allele after one generation of selection? (Note: provide both values to the nearest 0.0001)

In a species of snail (Snail 1), a locus has two alleles, A and B. The snail has populations on a continent and a small nearby island. The frequency of allele A on the continent is 0.7, and the frequency of allele A on the island is 0.2. If the migration rate, m, from the continent to the island is 0.1 (assume no migration from island back to continent), What is the change in the frequency of allele A after the first generation, compared to the original population?

Consider a gene with two alleles, L and M, that exhibit complete dominance. The table below provides the relative fitnesses of the three genotypes in two populations. LL LM MM Population 1 0.8 0.3 0.3 Population 2 0.9 1.0 1.0 a. Which allele is dominant, and how do you know? b. Which allele will increase (in each population), and how do you know? c. In which population will the change in allele frequencies occur more quickly, and how do you know?
