Sex Chromosomes. Sex chromosomes are particular chromosomes that are involved in determining the sex of an organism. In the cells of humans and many other organisms the sex chromosomes consist of a pair of chromosomes called the X and Y chromosomes. The X and Y chromosomes were first discovered in beetles by Nettie Stevens in 1906.
Sex chromosomes determine whether you are male or female. An individualâs sex (i.e., whether they are a male or female) is determined by the sex chromosomes. Most people have two sex chromosomes, one that is inherited from their mother and one that is inherited from their father. Typically, females have two X chromosomes (XX) and males have one X chromosome and one Y chromosome (XY).
