Explanation:
Given
Crossing of a black chicken and a white chicken
Required
The probability of having erminette chicks
The genotype of a black chicken is represented as: BB
The genotype of a white chicken is represented as: WW
The genotype of an erminette chicken is represented as: BW
Using a Punnett square, we have:

The result of crossing the two chicken gives 4 BW out of a total of 4
i.e 4 erminette chickens out of 4 possible chickens
So, the probability is:


Represent as percentage:
