Chromosomes

Meiosis plays a role in the genetic differences between the individuals of a species.

In order for an organism to develop gametes (cells such as sperm and eggs) to aid in sexual reproduction, a process known as meiosis must occur. Meiosis reduces the number of chromosomes found within the cell from 46 to 23 in humans.

When studying genes and genetics, it is important to understand some of the common terms associated with the study of genes.

There are four phases involved in the process of cell division known as mitosis; prophase, metaphase, anaphase and telophase.

Men with Klinefelter Syndrome possess an extra X chromosome. This makes their genetic makeup consist of 47 chromosomes rather than 46. The condition creates sex chromosomes that are represented as XXY as opposed to the normal XY male chromosomes.
