7. In some chickens, the gene for feather color is controlled by codominance. The allele for black is B and the allele for white

kondor19780726 [428]

Answer:

See the answer below

Explanation:

Genotype is the genetic composition of organisms and a gene is made up of two alleles.

a) Since the allele for black is B, the genotype for black chickens would be BB.

b) Since the allele for white is W, the genotype for white chickens would be WW.

c) Since erminette color is heterozygous, the genotype would be BW.

d) Two erminette were crossed:

BW x BW

BB BW BW WW

i. Probability of having black chick (BB) = 1/4

ii. Probability of having a white chick (WW) = 1/4

iii. Probability of having erminette chicken (BW) = 1/2
