Which of the following statements is true of a species that has a chromosome number of 2n = 16?
A) The species is diploid with 32 chromosomes per cell.
B) The species has 16 sets of chromosomes per cell.
C) Each diploid cell has eight homologous pairs of chromosomes.
D) A gamete from this species has four chromosomes.

Question

Quizplus · Accepted Answer

A species with a chromosome number of 2n = 16 is diploid, meaning it has two sets of chromosomes. Therefore, each diploid cell has eight homologous pairs of chromosomes. A gamete from this species would have only one set of chromosomes, or n = 8. Therefore, it would have four chromosomes. Option A is incorrect because it suggests that each diploid cell would have 32 chromosomes, which is double the correct number. Option B is incorrect because it suggests that the species has 16 sets of chromosomes, which is incorrect as the chromosome number per set is 8. Option D is incorrect because it suggests that a gamete from this species would have only two chromosomes, which is half of the correct number.
