How is the sex of the child determined in human beings?

Explanation

The two sexes participating in sexual reproduction must be somewhat different from each other for a number of reasons. In human beings, the sex of the individual is largely genetically determined. In other words, the genes

inherited from our parents decide whether we will be boys or girls. But so far we have assumed that similar gene sets are inherited from both parents. All human chromosomes are not paired. Most human chromosomes have a maternal and a paternal copy, and we have 22 such pairs. Among them one pair is called the sex chromosomes. Women have perfect pair of sex chromosomes called XX, where as in men they are different and are called XY.A child who inherits an X-chromosome chromosome from him will be a boy as shown in fig.
