Parents produce the following gametes:

Parent 1: C, c

Parent 2: c, c

The offspring genotypes are:

50% Cc, 50% cc.

If the blue allele was dominant, all the offspring would be blue. However, since the ratio of genotypes is the same as the ratio of phenotypes, the allele C is dominant and the allele c is recessive.

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...

R is the allele for red petals and r is the allele for blue petals which term describes the offspring of the cross represented by flower Z

When ever the R gene is present in the genotype of a plant, the flower color is always red. The mutant form of this gene, which is recessive, is often...

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, if P represents the dominant allele for extra fingers and toes (polydactyly) and p is the recessive 5-fingered allele, which of these genotypes would indicate a person with five fingers?

A person with five fingers will be homozygous recessive and he can have only one genotype possible- pp.PP and Pp genotype would indicate polydactyly.

A disease causing allele is recessive. Assume that the male parent doesn’t have the disease and the female parent has the disease. What percentage of sons will have the disease?

Let assume that the disease-causing allele is a and healthy allele is A. As the female parent has the disease, it could be assumed that the genotype of the female...

2.6) If two animals heterozygous for a single pair of alleles are mated and have 200 offspring, about how many would be expected to have the phenotype of the dominant allele?

When a dark blue fish and a light blue fish with dark blue fins were mated , all offspring became dark blue. What could also be seen was that part of the offspring got light gray fins.

Incomplete dominance because there is blending of colours.
