A female cat (a queen or a molly) and a male cat (tom or tomcat) produces offspring. We want to determine the likelihood that the kittens will inherit a genetic condition. The dominant allele (D) produces the normal phenotype, and the recessive allele (d) produces the genetic condition. Both the male and female cats have the normal phenotype.

Question

Using the allele symbols D and d, identify all possible genotypes of the female cat for this genetic condition.

Answer 1

Since both the male and female cats have the normal phenotype, they must both have at least one dominant allele (D).

Possible genotypes of the female cat for this genetic condition could be:
1. DD
2. Dd
