Question

Considering an organism with three pairs of homologous chromosomes, how many different kinds of gametes can this organism produce based on different chromosomal arrangements? Assume that the members of each pair are not identical?

Expert Solution

Step 1

Answer : Since there are 3 pairs of homologous chromosomes, therefore

2N = 6

N = 3

to Calculate the number of different possible combination of chromosomes, we have formula :

2ⁿ = number of different possible combinations

n = number of different chromosomes which here is 3 as mentioned to be assume the members of each pair being non-identical

hence, 2ⁿ= 2³ = 8
