A common trait found in orange tabby cats is the following: being awesome (A) is dominant to being average (a).

A male cat that is homozygous dominant for the A trait is mated with a female cat that is homozygous recessive.
For a cross with four offspring, what is the probability that they will have an offspring who is heterozygous?

To determine the probability of having an offspring who is heterozygous, we can first determine the possible genotypes of the offspring from the parents' genotypes.

The male cat is homozygous dominant (AA) for the A trait, and the female cat is homozygous recessive (aa). When these two cats are mated, all the offspring will be heterozygous (Aa).

Therefore, the probability of having an offspring who is heterozygous is 4 out of 4, or 100%.
