Assume a particular organism has a diploid chromosome number

Assume a particular organism has a diploid chromosome number of 4. How many different chromosome combinations can be normally packaged among the gametes of this organism? (Assume that no crossing over occurs.)

Solution

Diploid chromosome number of organism is 2n = 4. The chromosome can be packed into gametes in 4 different ways (2² = 4).

2ⁿ , Where n is haploid number. In this case it is, 2² .

There is no crossing over and each chromosome can contribute in the gamete formation. Therefore, 4 different combinations are possible to form gametes in this organism.
