If the homozygous dominant genotype makes up 36% of the population what is the frequency of the dominant allele in that population?
According to the Hardy-Weinberg Law (p^2+2*p*q+q^2=1) a frequency of the homozygous dominant genotype is p^2 = 36%/100= 0.36, therefore the frequency of the dominant allele in that population is the...

Parent 1 is red (Cc) and parent 2 is blue (cc). The offspring in the F1 generation are 50% red and 50% blue. Which allele is dominant? Which allele is recessive?
Parents produce the following gametes:Parent 1: C, cParent 2: c, cThe offspring genotypes are:50% Cc, 50% cc.If the blue allele was dominant, all the offspring would be blue. However, since...

A population of squirrels have 250 red-sided individuals and 750 tan-sided individuals. Assume that red is totally recessive. Calculate the allele frequencies of each allele.
Red-sides animals result from occasional combination between two recessive alleles. This even happens with the probability, which is equal to squared frequency of the recessive allele in population. The frequency...

The frequency of a recessive allele in a large randomly mating population is 0.2.
What is the frequency of:
(a) The dominant allele?
(b) The heterozygote
a. q=0.2, and p+q=1. Thus, the frequency of dominant allele is 1-0.2=0.8 b. The frequency of heterozygote is 2*p*q. It is 2*0.8*0.2 = 0.32

In humans, diabetes is a sex-linked recessive trait. If a homozygous normal woman and a man, whose mother is a diabetic, have children, what will be the phenotypes and genotypes of their children?
If woman is normal homozygous, she has genotype XD XD. If mother of her husband is diabetic, he has genotype XdY and also is diabetic.So if they have children, they...

. A man who is homozygous dominant for blue hair marries a woman with green hair. They have four children. Predict the children’s’ genotypes and phenotypes
Let's assume that B is a blue hair allele and b is a green hair allele. As a result, the parental genotypes are:Male - BB, possible gametes - B;Female -...
