Which is true of a species that has a chromosome number of 2n= 16?
A
species is diploid with 32 chromosomes per cell
B
species has 16 sets of chromosomes per cell
C
each diploid cell has 8 homologous pairs
D
a gamete from this species has 4 chromosomes
Explanation: 

Detailed explanation-1: -Answer and Explanation: The correct answer here should be A, that each diploid cell has 8 pairs of homologous chromosomes. Since this organism has a 2n ploidy number of 16, it means that each of their diploid cells will have 16 chromosomes, 8 pairs of homologous chromosomes.

Detailed explanation-2: -Chromosome Number of Onion The chromosome number is 2n = 16.

Detailed explanation-3: -The organism is diploid and it has 16 chromosomes. 2n = 16, n is the haploid number of chromosomes. 2n = 16, it means n = 8. The haploid number of chromosomes is 8.

Detailed explanation-4: -Answer and Explanation: For a cell that has a chromosome number 2n=30: c. The cell has two sets of 15 homologous chromosomes.

Detailed explanation-5: -D. The species is diploid with 32 chromosomes per cell.
