Question

According to the law of independent assortment, how many different types of gametes would be produced if the genotype is AabbCcDD?

• A. 4
• B. 6
• C. 8
• D. 10
• E. 12

Answer 1

The correct option is A 4

In accordance to Mendel's law of independent assortment, the number of gametes formed in any genotype/ individual is directly related to the number of heterozygous genes present in pairs on homologous chromosomes (n). The relation is given as 2${}^n$, where n is the number of heterozygous gene pairs. In this case we have 2 pairs of such genes Aa and Cc. DD and bb are homologous pairs and will not cause different combinations on their own. therefore the correct answer is 2${}^2$='4'.
