Function of Chromosomal Sex

Explanation:

• Sex chromosome, both of a pair of chromosomes that decide if an individual is male or female
• The sex chromosomes of individuals and different vertebrates are assigned by researchers as X and Y
• In humans the sex chromosomes involve one sets of the total of 23 sets of chromosomes and The another 22 sets of chromosomes known as autosomes
• Individuals having two X chromosomes (XX) are female such as individuals having one X chromosome and one Y chromosome (XY) are male
• The X chromosome belongs like an enormous autosomal chromosome with a long and a short arm and The Y chromosome has one long arm and a brief second arm
• Another way to maleness or femaleness originates at the moment of meiosis, when a cell partitions to deliver gametes, or sex cells having a large portion of the typical number of chromosomes. During meiosis the male XY sex-chromosome pair isolates and gives a X or a Y to isolate gametes
