A common trait found in orange tabby cat is the following: awesome (A) is do to being average (a). A male cat that is homozygous dominant (A) trait is mated with a female cat that is homozygous recessive. What is the probability that they will have an offspring who is heterogeneous. Blank out of black

1 answer

In this genetic scenario, we can use basic Mendelian genetics to determine the probabilities of the offspring's traits.

  1. Identify the genotypes of the parents:

    • The male cat is homozygous dominant (AA).
    • The female cat is homozygous recessive (aa).

  2. Determine the genotypes of the offspring: When these two cats are mated, all offspring will receive one allele from each parent:

    • Male contributes: A
    • Female contributes: a

    Therefore, all offspring will have the genotype Aa (heterozygous).

  3. Calculate the probability of the offspring’s genotype: Since all offspring in this cross will be Aa, the probability of having an offspring that is heterozygous (Aa) is 100% or 1.

So the final answer is: 1 out of 1 (which is equivalent to saying 100%).
