To prepare the 46 chromosomes of a human cell for transport to the daughter cells during cell division, each chromosome forms a compact X-shaped structure with two rod-like copies.

In humans, that means carefully packaging 46 chromosomes and distributing them equally. Before division, each chromosome transforms into a compact, X-shaped structure made of two identical, rod-like ...

So 23 of your 46 chromosomes come from a parent egg cell, and the other 23 come from a parent sperm cell. Scientists number the first 22 of these pairs 1 through 22.

Humans contain 46 chromosomes (23 pairs), out of which the last 23rd pair of chromosomes is known as the sex chromosome. Females have only XX chromosomes, while males have a combination of XY ...

Humans have 23 pairs of chromosomes, or 46 total, and 22 of these pairs are numbered chromosomes, known as autosomes. The 23rd pair is a pair of sex chromosomes (XX or XY).
