a pure breeding white cat (homozygous dominant) mates with a pure breeding black cat (recessive), what would be the fur colour of F1 generation
Answer Details
In this scenario, the white cat is homozygous dominant, meaning it has two copies of the dominant white gene. The black cat is homozygous recessive, meaning it has two copies of the recessive black gene. When the two cats mate, their offspring (F1 generation) will all inherit one copy of the white gene from the white cat and one copy of the black gene from the black cat, making them all heterozygous. However, since the white gene is dominant over the black gene, the F1 generation will all have white fur. Therefore, the answer is "Heterozygous white."
