Chromosomes are structures of nucleic acids and proteins found in the nucleus of a cell. They contain all the genetic information of an organism. Humans have 46 pairs of chromosomes, with half from each parent. Which of the following best describes why the offspring will receive only half of the parents' chromosomes?

A) Chromosomes assort independently, and crossing-over occurs.

B) Gametes contain homologous pairs from the mother and father.

C) Diploid eukaryotic cells become haploid before fertilization.

D) The cell cycle stops, allowing for extra haploid cells to be made.
