Question

C. In the long run. What will happen to the frequencies of the "C" and "c" alleles in this population? 29. You Africa and have identified a newly arisen (by mutation) allele at the C locus. The initial allele frequency of the mutant allele "c" is 0.01. You have also determined that the allele acts additively. On a moonless night, you genotype nesting females and count the number of eggs they lay. You find that, on average, "CC" females produce 98 eggs, "Cc" produce 99 eggs, and "cc" produce 100 eggs. In this species of crocodile, all eggs hatch and survive to maturity. are studying a very large population of crocodiles on the Nile River in a. Will the "c" allele increase, decrease, or stay the same in the next generation? b. Will you likely be able to observe the change in the allele frequency? Why?

Explanation / Answer

(a)

The "c" allele frequency will increase in the next generation because a "cc" females prodeuce 100 eggs while "Cc" produce 99 eggs so the chance of a "c" allele to passed into next generations is more because "CC" females produce 98 eggs which is less than taht of "cc" and "Cc" . So the frequency of "c" allele will increase in next generation.

(b)

Yes we are likely to observe the change in allele frequency because allele frequency is calculated by dividing the number of times the allele of interest is observed in a population by the total number of copies of all the alleles at that particular genetic locus in the population. Initially allele frequency of "c" = 0.01 but as mating happens and more individuals are born the number of times the "c" allele occurs in the population will be more . So the number of times "c" allele is observed will be more hence the frequency of allele can be observed.

(c)

In the long run the frequency of "C" allele will be less and the frequency of "c" allele will be more because "cc" individuals will be more hence the "c" allele frequency will be more compared to "C" allele whose frequency is less because "CC" individuals are less . So , frequency of "c" allele will be more and frequency of "C" allele will be less.
