Question

Question 4 (4 pts). A population of poisonous frogs is sampled and assessed for skin color. Skin color is determined by alleles at one locus; allele "C" is for Blue skin and allele "c" is for red skin. "C" is completely dominant to "c" Assume that this population is in Hardy-Weinberg Equilibrium and that the population's features and the locus for skin color satisfy the assumptions for the H-W Law. From a population of 462 poisonous frogs, 174 frogs have blue skin and 288 frogs have red skin. a. What is the frequency of the allele for red skin, allele "c? b. What is the frequency of allele C? What is the expected frequency of the "cc" genotype in the next generation of that population c. d. What is the expected frequency of the "Cc" genotype in the next generation of that population?

Explanation / Answer

A. Allele frequency for red skin (c) is 62.33% (divide 288/462).

B. Allele frequency for blue skin (C) is 37.66% (divide 174/462).

This verifies as both the allelic frequencies add upto 1.

C. Expected genotypic frequency of 'cc' genotype is 62.33%. Same as above answered. This is because the genotype is recessive and given in the data.

D. Expected genotypic frequency of 'Cc' genotype is 18.83%. Divide the blue skin allelic frequency into two (37.66/2). This is because, the blue skin population comprises of both 'CC' and 'Cc' ('C' is dominant over 'c').
