What is a statement is true of x chromesomes?

X chromosomes are one of the two sex chromosomes in humans, with females typically having two (XX) and males having one (XY). They carry a significant number of genes, including those related to sex determination and various other traits and conditions. Additionally, X chromosomes undergo a process called X-inactivation in females, where one of the X chromosomes is randomly silenced to ensure dosage compensation between the sexes. This unique characteristic contributes to the complexity of genetic expression and inheritance in humans.
