Answer Details

Assuming that in sheep, the allele for black coat colour is dominant over that for brown coat colour, crossing a heterozygote black with a homozygote brown will result in 50% of the offspring having a black coat colour and 50% having a brown coat colour. This is because the heterozygote parent carries one dominant black allele and one recessive brown allele, and the homozygote brown parent carries two recessive brown alleles. Therefore, the possible combinations of alleles for the offspring are BB (black), Bb (black), and bb (brown). The probability of each outcome is 50% black and 50% brown.
