The frequency of allele a is 0.4 for a population in Hardy-Weiberg equilibrium. What is the expected frequency of genotype Aa?

Homework Answers

Answer #1

This is a population in Hardy-Weiberg equilibrium,

In this problem the recessive genotype is represented by (aa) and dominant genotype as (AA).

Given

The frequency of the allele “a” is represented by “q” is 0.4

So the frequency of the allele “A” is represented by “p” where p+q=1; p+0.4=1

So “p”= 0.6

The frequency of genotype is represented by “AA”, “aa”, “Aa”.

The frequency of genotype, “AA”=p=

The frequency of genotype, “aa”=q=

The frequency of genotype, “Aa”= 2pq=

The expected genotypic frequency is

19.If the frequency of the sickle cell allele in a particular population is 0.12, what is the frequency of heterozygotes? What percentage of the population is expected to have sickle cell disease? 20.In the previous problem, I suspect you applied the Hardy-Weinberg equation (if not: GIGANTIC HINT). However, a frequency of the sickle cell allele that high is likely only to exist in a population where malaria is endemic - it’s not expected to be that high elsewhere. Given that...
