Suppose that you mated a black male rabbit with a white female rabbit and that the female gave birth to eight bunnies. If white is dominant to black and the female is heterozygous for hair color, how many of the bunnies are likely to be black?
You can draw a Punett square to see, but i'd need to know the male's genes to see. It might be a 1/2 and 1/2 chance, but if the male had a recessive white gene, it would change the equation.
