● It has already been mentioned that the `color{Violet}"sex determining mechanism"` in case of `color{Violet}"humans is XY"` type.
● Out of 23 pairs of chromosomes present, `color{Violet}"22 pairs"` are exactly `color{Violet}"same"` in both males and females; these are the `color{Violet}"autosomes"`.
● A `color{Violet}"pair of X-chromosomes"` are present in the female, whereas the presence of an `color{Violet}"X and Y chromosome"` are determinant of the male characteristic.
● During `color{Violet}"spermatogenesis"` among males, `color{Violet}"two types"` of gametes are produced.
● `color{Violet}"50 per cent"` of the total sperm produced carry the `color{Violet}"X-chromosome"` and the rest `color{Violet}"50 per cent"` has `color{Violet}"Y-chromosome"` besides the autosomes.
● Females, however, produce only `color{Violet}"one type of ovum"` with an X-chromosome.
● There is an `color{Violet}"equal probability of fertilisation"` of the ovum with the sperm carrying either X or Y chromosome.
● In case the ovum fertilises with a sperm carrying `color{Violet}"X-chromosome"` the zygote develops into a `color{Violet}"female (XX)"` and the fertilisation of ovum with `color{Violet}"Y-chromosome"` carrying sperm results into a `color{Violet}"male offspring"`.
● Thus, it is evident that it is the `color{Brown}"genetic makeup of the sperm"` `color{Violet}"that determines the sex of the child"`.
● It is also evident that in each pregnancy there is always `color{Violet}"50 per cent probability"` of either a male or a female child.
● It is unfortunate that in our society `color{Violet}"women are blamed"` for producing female children and have been ostracised and ill-treated because of this false notion.
