Final answer:
The possible gametes produced by an individual with genotype AaBb, during normal meiosis, are AB, Ab, aB, and ab, representing all combinations of one allele from each gene.
Step-by-step explanation:
The question is centered on the types of gametes that can be produced by an individual with the genotype AaBb. During meiosis, paired alleles segregate independently and are distributed into separate gametes. Therefore, the possible gametes produced will include one allele from each gene. For the gene Aa, the gametes could have either A or a, and for the gene Bb, either B or b. Combining these possibilities results in the following types of gametes: AB, Ab, aB, and ab.
Nondisjunction is an error in meiosis where chromosomes fail to separate properly, but it is not relevant to the production of standard gametes, as it leads to abnormal chromosome numbers in the gametes. When meiosis proceeds normally without nondisjunction, four varied haploid gametes are produced. For instance, if an organism with a genotype of AaBb undergoes meiosis, the gametes will assort independently and result in the combination of alleles as AB, Ab, aB, and ab (Option c).
