How is maleness and femaleness determined?
Gender is determined by the male sex cells. We have 46 chromosomes, and haploid sex cells contain 23. The female sex chromosomes are both X, while male has two different forms of the chromosome (X and Y). So about half of the male sex cells have an X chromosome, and about half have the Y chromosome. When egg is fertilized, the 23 chromosomes of the female egg (an X) and the 23 chromosomes of the sperm (X or Y) fuse together to total 46. The sperm determines the gender because if it has X it will be a girl (XX) and if it has Y it will be a boy (XY). There are various means suggested to increase the ratio of X or Y sperm that are contained in the semen, in order to increase the chances for either a girl or boy baby.
