Question

Which of the following 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 cell has eight homologous pairs.
d)A gamete from this species has four chromosomes.

Answer 1

A species with a chromosome number of 2n= 16 is diploid, with 32 chromosomes per cell. However, a gamete from this species will have four chromosomes.

Step-by-step explanation:

A species with a chromosome number of 2n= 16 is diploid. This means that each somatic cell of the organism contains two sets of chromosomes. In this case, there are 16 chromosomes in each set, totaling to 32 chromosomes per cell.

A gamete from this species, which is a haploid cell, will have half the number of chromosomes as a somatic cell. Therefore, a gamete from this species will have 16 chromosomes.

The correct option in this case is d) A gamete from this species has four chromosomes.
