X is for X Chromosomes #atozchallenge

The human body is composed of 22 pairs of chromosomes and one pair of sex chromosomes. The female has two X chromosomes while the male has one X chromosome and one Y chromosome.

The female receives one X chromosome from her mother and one X chromosome from her paternal grandmother.

Males have only one X chromosome so they are likely to suffer from genetic X chromosome diseases.
The first X chromosome was isolated in 1890.

  1. Actually females get an X chromosome from their mother and another from their father.
