Question

for a certain breed of cat short tails are dominant t and long tails are recessive t. the punnett square shows a cross between two parents. what is the phenotype ratio for this cross?

Answer 1

In the Punnett square, we have 100% Heterozygous Dominant. I'm assuming cats tails follow simple Mendelian Inheritance and none of the Incomplete Dominance, Co-Dominance, Pleotropism phenomena.
The T indicates the dominant short tail, and t the recessive long tail.
