In our society a woman is often blamed for not bearing male child. Do you thing it is right? Justify.

Explanation

It is unfortunate that in our society women are blamed for giving birth of female children and have been ostracised and ill-treated because of this false notion. Out of 23 pairs of chromosomes present, 22 pairs are axactly same in both males and frmales, these are the autosomes.
A pair of X-chromosomes are present in the femele, whereas the presence of an X and Y-chromosome are determinant of the male characteristic. During spermatogenesis among males, two types of gametes are produced.
50 per cent of the total sperm produced carry the X-chromosome and the rest 50% has Y-chromosome besides the autosomes. Femels, however, produce only one type of ovum with an X-chromosome. These is an equal probability of fertilisation of the ovum wiht the sperm carying either X or Y-chromosome.
In case when the ovum fetilises with a sperm carrying X-chromosome the zygote develops inot a frmale (XX) and the fertilisation of ovum with Y-chromosome carrying sperm results into a male offspring. Thus it is evident that it is the genetic makeup of the sperm (male) that determines the sex of the child.
It is also evident that in each pregancy there is always 50% probability of having either a male or a female child.
