Question

Quizplus · Accepted Answer

When an organism is heterozygous for two traits, it means that it carries two different alleles for each trait. This can be represented as AaBb. During meiosis, the alleles on homologous chromosomes can undergo independent assortment, meaning that they can segregate into different gametes. This leads to the production of four different gamete combinations: AB, Ab, aB, and ab. Therefore, the maximum number of different gametes that an organism that is heterozygous for two traits can produce is four.
