Intercourse chromosomes are specific chromosomes which are associated with determining the intercourse of a system.
Into the cells of people and several other organisms the sex chromosomes contain a couple of chromosomes called the X and Y chromosomes. The X and Y chromosomes had been first found in beetles by Nettie Stevens in 1906. She realized that cells of feminine beetles had identical searching pairs of each and every of the a few chromosomes, but that male beetles had one set when the chromosomes had been different in features from one another. She called those two chromosomes the X in addition to Y, and discovered that feminine beetles differed from males in containing two X chromosomes.
