Detailed explanation-1: -Two of the chromosomes (the X and the Y chromosome) determine your sex as male or female when you are born. They are called sex chromosomes: Females have 2 X chromosomes. Males have 1 X and 1 Y chromosome.

Detailed explanation-2: -In this system, the sex of an individual is determined by a pair of sex chromosomes (gonosomes). Females have two of the same kind of sex chromosome (XX) and are called as the homogametic sex. Males have two distinct sex chromosomes (XY) and are called as the heterogametic sex.

Detailed explanation-3: -These include 22 pairs of “autosomes” (which refers to all chromosomes that are not sex chromosomes) and a pair of sex chromosomes, either an X and a Y (which makes for a male) or two Xs (female). That means the genetic signature for a person with 46 chromosomes is either 46, XY (males), or 46, XX (females).

Detailed explanation-4: -In humans there are 6 common sex karyotypes: XX, XY, XXY, XXXY, & XYYY. & there are 4 rare sex karyotypes: XO, XO/XX mosaicism, XY/XXY mosacism, XXY/XXXY/XXXXY mosaicism.

Detailed explanation-5: -… A sex chromosome is a type of chromosome involved in sex determination. Humans and most other mammals have two sex chromosomes, X and Y, that in combination determine the sex of an individual. Females have two X chromosomes in their cells, while males have one X and one Y.
