Question

1. How many different types of gametes can be formed by individuals of the following genotypes, and what are the gametes in each case? а. AаBb b. AаBB с. AаВbСс d. AaBBcc e. AaBbcc f. AaBbCcDdEe

Answer 1

Genotype of gametes -
• Types of gametes depends upon each pair of heterozygous genes.(*In diploid organisms, heterozygous refers to an individual having two different alleles).

• When gametes are produced, members of a gene pair separate into different gametes. Therefore, we must separate the genes while making the gamete combinations.
