Chromosome

Men have an X and Y chromosome; women, two Xs.

Your chromosome can undoubtedly show what kind of human you are!

I know I'm a man because I've got a penis and I have a male chromosome pair.

If you have a male chromosome pair, you're a man.

In biology, if you have a male chromosome pair, you're a man. If you disagree with that, that's your problem, not the problem of the scientific world.

Every single chromosome in your body cries out that you're a man.

This engineered chromosome belongs to yeast, but experts say it can help them understand how genes work in humans as well.

A karyotype may be used to look for abnormalities in chromosome number or structure.

Each chromosome has a constriction point called the centromere, which divides the chromosome into two sections, or “arms.”

Heterozygosity, which is the presence of two different alleles or minor variations of the same gene at a given position on a chromosome, apparently benefits the herd.
