Answer:
See the answer below
Explanation:
<em>Genotype is the genetic composition of organisms and a gene is made up of two alleles.</em>
a) Since the allele for black is B, <u>the genotype for black chickens would be BB. </u>
b) Since the allele for white is W, <u>the genotype for white chickens would be WW.</u>
c) Since erminette color is heterozygous,<u> the genotype would be BW.</u>
d) Two erminette were crossed:
BW x BW
BB BW BW WW
i. <em>Probability of having black chick (BB) </em>= 1/4
ii. <em>Probability of having a white chick (WW)</em> = 1/4
iii. <em>Probability of having erminette chicken (BW)</em> = 1/2
