The X chromosome is one of the two sex chromosomes in humans and most other mammals, playing a crucial role in determining sex and carrying genes essential for various biological functions. Unlike the Y chromosome, which is present only in males, the X chromosome is present in both males and females, with females having two copies and males having one.

Sex chromosomes are specialized chromosomes that determine the sex of an organism and are typically represented as X and Y in mammals, where XX denotes female and XY denotes male. These chromosomes carry genes that are crucial for the development of sexual characteristics and can also influence other biological traits.

The Y chromosome is one of the two sex chromosomes in humans, responsible for determining male biological characteristics and playing a crucial role in male fertility. It carries genes that are essential for the development of male reproductive organs and the production of sperm, but it is significantly smaller and contains fewer genes than its counterpart, the X chromosome.

Biological functions refer to the roles and activities performed by various structures within living organisms that contribute to their survival, growth, and reproduction. These functions are complex, interdependent, and regulated by genetic, biochemical, and environmental factors to maintain homeostasis and adapt to changing conditions.
