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?
____out of ____
To determine the probability of having an offspring that is heterozygous (Aa), we need to consider the genotypes of the parents.
The male cat is homozygous dominant for the A trait, so its genotype is AA.
The female cat is homozygous recessive, so its genotype is aa.
When these two cats mate, all of their offspring will be heterozygous (Aa) because each offspring will inherit one dominant allele (A) from the male and one recessive allele (a) from the female.
Therefore, the probability of having an offspring that is heterozygous is 1 (all four offspring will be heterozygous).
The probability is 1 out of 1, or simply 1.

When these two cats mate, their offspring will have the following possibilities:
- 100% chance of being heterozygous (Aa) because each offspring will inherit one dominant allele (A) from the male and one recessive allele (a) from the female.
Therefore, the probability of having an offspring that is heterozygous is 100%.
The probability is 100% out of 100, or simply 1.
