Answer to Question #170171 in Genetics for Sameer

Question

In rabbits, black hair is dominant to chocolate hair and straight ears are dominant to floppy ears. A male who is homozygous for both black hair and floppy ears is crossed with a chocolate female who has straight ears. Her father had floppy ears. (A) What would be the frequency of rabbits with chocolate hair? (B) If they had 30 baby rabbits, how many would have black hair and straight ear *

Answer 1

An 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. 

A. Frequency

1 = p² + 2pq + q²

BBee + bbEe

frequency therefore is 1

B. Baby rabbits that will have black hair and straight ears will be 16
