Answer Details
In man, sex is determined by the inheritance of a pair of sex chromosomes, which are also known as X and Y chromosomes. Females inherit two X chromosomes, while males inherit one X and one Y chromosome. The presence of the Y chromosome determines maleness, while the absence of it results in femaleness. Therefore, the inheritance of a specific combination of sex chromosomes determines the sex of an individual.
