Determination of sex in human beings

INTRODUCTION

In human beings, there are 23 pairs(46) chromosomes in each body cell. Of these, 22 pairs are called autosomes and have no direct effect on the sex of the individual. One pair is directly concern with sex determination. This one pair (two chromosomes) is referred to as sex chromosomes.

In the male child the two sex chromosomes in each body cell are called X and Y. Each male gamete carries either X or a Y chromosomes. In the female, all the cells of the body contains two X chromosome.
All eggs contain one chromosomes each.

EXPLANATION/PROCESS

At fertilization, the combination of an egg with a sperm carrying either an X or a Y chromosome occurs by chance. The chances of an egg combining with either of the two types of sperm are equal. If a sperm with an X chromosome combines with an egg (having X chromosome), the zygote has two X chromosomes and forms a female baby and vice versa.

So you see the determination of the sex of a human being is determined by the Father
