X-chromosome
X-chromosome
The X-chromosome (pronounced: eks-kroh-muh-sohm) is one of the two sex-determining chromosomes in many animal species, including humans. The other is the Y-chromosome.
Etymology
The term "X-chromosome" was coined by the American geneticist and biologist Thomas Hunt Morgan. The "X" refers to its unique properties of inheritance, as it was the first chromosome to be discovered and studied in detail.
Function
The X-chromosome carries a larger number of genes compared to the Y-chromosome. It is involved in the determination of sex, as well as in the development and functioning of several body systems.
