What are the possible genotypes for the offspring?

The correct choice indicates that the possible genotype for the offspring is "Aa." This genotype suggests a heterozygous condition, where one allele is dominant (represented by "A") and the other is recessive (represented by "a"). In genetic crosses, particularly those involving Mendelian inheritance, offspring receive one allele from each parent.

The presence of the "A" allele implies that at least one parent must carry this dominant trait, while the "a" allele shows that the other parent contributes a recessive trait. This combination is crucial for predicting traits in offspring. In scenarios involving a dominant and recessive allele, "Aa" offspring can exhibit the characteristics associated with the dominant allele while still carrying the potential to pass on the recessive allele.

In contrast, the other choices do not convey the same potential genetic contribution from the parents to create a combination that includes both dominant and recessive traits for this particular case.
