Question

Which statement correctly compares the number of chromosomes in a body cell to that in a sex cell of humans?

A. A body cell has 21 chromosomes; a sex cell has 23

B. A body cell has 21 chromosomes; a sex cell has two

C. A body cell has 46 chromosomes; a sex cell has 23

D. A body cell has 46 chromosomes; a sex cell has two

Answer 1

The answer is C: "A body cell has 46 chromosomes; a sex cell has 23"

Answer 2

Answer is: C. A body cell has 46 chromosomes; a sex cell has 23.

Chromosome is a DNA molecule with part or all of the genetic material of an organism.

Chromosomes in humans are divided into two types:

1) body chromosomes or autosomes.

2) sex chromosomes or allosomes.

When sex cells unite during fertilization, the haploid cells (23 chromosomes) become a diploid cell (46 chropmosomes).

Body cells have 23 pairs of chromosomes (22 pairs of autosomes and one pair of sex chromosomes), giving a total of 46 per cell.
