The male cat is homozygous dominant, meaning it has two copies of the A allele (AA). The female cat is homozygous recessive, meaning it has two copies of the recessive a allele (aa).
When these cats mate, each parent can only contribute one allele to their offspring. The male cat can only contribute the A allele, and the female cat can only contribute the a allele.
The possible genotypes for the offspring are:
1. AA
2. Aa (heterozygous)
3. Aa (heterozygous)
4. aa
Since only 2 out of the 4 possible genotypes (AA, Aa, Aa, aa) are heterozygous (Aa), the probability of having an offspring who is heterozygous is 2 out of 4 or 1 out of 2.
Therefore, the probability of having an offspring who is heterozygous is 1/2 or 0.5.
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.
What is the probability that they will have an offspring who is heterozygous? out of
