The diploid number of a roundworm species is 4.Assuming there is no crossover,and there is random segregation of homologues during meiosis,how many different possible combinations of chromosomes might there be in the offspring?

Question

Quizplus · Accepted Answer

The possible number of combinations in the offspring can be calculated using the formula 2^n, where n is the haploid number of chromosomes. In this case, the haploid number is 2 (as diploid number is 4), so 2^2 = 4 possible combinations of chromosomes can be produced. However, since each parent contributes one set of chromosomes, the total number of possible combinations in the offspring is 4 x 4 = 16. Therefore, the best choice is D) 16.
