Question

A trihybrid cross involve three pair of characters, which will give rise to the F${}_1$ hybrids, which are heterozygous for three genes. How many types of gametes will be produced in both male and female?

• A. 2
• B. 4
• C. 6
• D. 8

Answer 1

The correct option is D 8

The total number of gametes produced by a genotype can be calculated using the formula 2${}^n$, where "n" is the total number of heterozygous genes present in the genotype. Since, the F${}_1$ hybrids are heterozygous for three genes, the types of gametes produced in both male and female will be 2${}^3$= 8. Hence, option D is the correct answer.
