12.In a zygote that begins with a complement of two homologous chromosomes pairs, A and a, and B and b: a.What chromosome compliments would you find in each somatic cells during growth? b.What combinations chromosomes would you expect to find in the gametes if the individual becomes an adult? Explain.
