Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Let’s say we are breeding bunnies with the allele combinations for fur (FF or Ff) and furless (ff). What is the gene frequency of the allele F if we have 40 F alleles and 60 f alleles?
A
100
B
.4
C
.6
D
2.5
Explanation: 

Detailed explanation-1: -Bunnies that inherit two F alleles or one F and one f allele have fur (FF or Ff), while bunnies that inherit two f alleles have no fur (ff).

Detailed explanation-2: -1A. The gene for hair color in rabbits has two alleles Q and q. Q is dominant and codes for brown hair. q is recessive and codes for white hair.

Detailed explanation-3: -Coat Colour in Rabbit The coat colour of rabbits is determined by the C gene. The C gene has multiple allelic forms that lead to varied phenotypes. The different phenotypes for coat colour in rabbits are agouti (full colour), chinchilla, Himalayan and albino. The four common allele of C gene are C, cch, ch and c.

Detailed explanation-4: -To find the allele frequencies, we again look at each individual’s genotype, count the number of copies of each allele, and divide by the total number of gene copies.
