The answer is C) Bb x Bb
B - the allele for black and white coloration
b - the allele for brown and white coloration
There are in total 11 offspring (8 black and white and 3 brown and white),
In a monohybrid cross when both parents are heterozygous (Bb), the phenotype ratio is 3:1. We have ratio 8:3.
The ideal ratio would be 9:3 because it is the same as 3:1.
Therefore, the parents Bb and Bb will have 8 black and white and 3 brown and white with the ration 8:3 ≈ 9:3 = 3:1
