Question

The law of independent assortment allows for genetic recombination. The following equation can be used to determine the total number of possible genotype combinations for any particular number of genes: 2g = Number of possible genotype combinations (where g is the number of genes)1 gene: 21 = 2 genotypes2 genes: 22 = 4 genotypes3 genes: 23 = 8 genotypesa) Consider the following genotype: YySsTt. How many different gamete combinations can be produced?

Answer 1

Gametes that will be produced are:

YST, YSt, YsT, Yst, yST, ySt, ysT, yst

Step-by-step explanation:

From YySsTt, it is obvious that as there 3 type of genes.

The number of gametes =
`2^(3)` = 8

5 genes =
`2^(5)` = 32 genotypes

10 genes =
`2^(10)` = 1024 genotypes

20 genes =
`2^(20)` = 1048576 genotypes
