Sex chromosomes are the genetic elements that define a person's biological sex Learn about the xx and xy chromosomes, the sex determination system, and other chromosome combinations. In this system, the sex of an individual usually is determined by a pair of sex chromosomes Typically, females have two of the same kind of sex chromosome (xx), and are called the homogametic sex. It is often assumed that women have xx chromosomes and men have xy, but biology is more complex Some women have xy chromosomes — a natural variation in sex development They grow up identifying and living as women, and most only discover well into puberty that they are different Danish researchers have, for the first time, mapped how many women have xy chromosomes Women have 22 normal chromosomes and 2 x chromosomes, ie 22 + xx, and men have 22 normal chromosomes and 1 x, 1 y, ie 22 + xy Through this mechanism, we understand that x chromosomes will regulate female, while y is male But if so, why don't men carry yy pairs? Females receive two x chromosomes, represented by xx Males receive an x and a y chromosome, represented as xy But where do the x and the y come from Like all chromosomes, the x and y chromosomes that determine gender are passed from parents to offspring To understand how this happens, let’s look at a special type of cell division called.
