How many different types of gametes can be formed by the $F_{1}$ progeny, resulting from the following cross?

$AABBCC \times aabbcc$

Options:

Answer:

Solution:

Types of gametes = 2ⁿ

n = number of heterozygotes considered i.e., monohybrid cross (n = 1), dihybrid cross (n = 2), trihybrid cross (n = 3) and so on.

$AABBCC \times aabbcc$ is a trihybrid cross, therefore, different types of gametes are:

= 2ⁿ

n = 3 = (2)³

$= 2 \times 2 \times 2 = 8$ .
