Final answer:
Genotype bA is normally not found in a gamete.
Step-by-step explanation:
The genotype that is normally not found in a gamete is: bA. Gametes are haploid cells, meaning they carry only one allele for each gene. In the given options, "bA" represents a combination of two different alleles for a specific gene (one from each parent). In gametes, alleles segregate, and only one allele is present for a particular gene. Therefore, "bA" as a combination of two different alleles is not a typical representation in a gamete. Gametes would typically carry one of the following genotypes: AB, ab, aa, or aB, where each represents a single allele for a specific gene.
