Jessica has two hamsters, one male and one female. The male hamster is brown, the dominant trait for hamsters. His genotype is Ff. The capital F represents the dominant trait for hamsters, which is brown fur. The lowercase f represents the recessive trait for hamsters which is white fur. The female hamster has white fur, the recessive trait for hamsters.

With these parents, there is a 50% chance of offspring whose phenotype (an organism's physical appearance) is heterozygous brown, and a 50% chance of an offspring whose phenotype is homozygous white.

What is the possibility of ever, with any two genotypes, having offspring whose phenotype is heterozygous white?
