Question Question 3(iii)
In a certain species of animals, black fur (B) is dominant over brown fur (b). Predict a genotype and phenotype of the offspring, when both parents are Bb or have heterozygous black fur.
| B | b | |
| B | BB | Bb |
| b | Bb | bb |
In the question it is given that B refers to black fur and b refers to brown fur. So the genotype and phenotype of the offspring will be:
Genotype — 1 (Homozygous Black Fur) : 2 (Heterozygous Black Fur) : 1 (Homozygous Brown Fur)
Phenotype — 3 (Black Fur): 1 (Brown Fur)
