The X or Y chromosome in human beings that determines the sex of an individual. Females have two X chromosomes; males have an X and a Y chromosome.

One of the two chromosomes that specify the sex of an organism. Humans have two kinds of sex chromosomes, one called the X and the other Y. Normal females possess two X chromosomes and normal males possess one X and one Y.

The pair of chromosomes responsible for determining the sex of an individual.

 Chromosomes that contain the genes that code for the development of male or female characteristics.

The cell structures carrying hereditary information that differentiate female from male in humans and other mammals. Females have a pair of X chromosomes. Males have one X chromosome and one Y chromosome.

The X and Y chromosomes; the unequal pairs of chromosomes involved in sex determination (which is based on the presence or absence of a Y chromosome). Females lack a Y chromosome and normally have the genotype XX; males have a Y chromosome and normally have the genotype XY. shock

Sex chromosomes are those chromosomes that influence sex determination. In mammals, including humans, the X and Y chromosomes are the sex chromosomes (females are XX, males XY). The chromosomes which [..]
