Long Answer Type
Short Answer TypeWomen are often blamed for producing female children. Consequently, they are ill-treated and ostracized. How will you address this issue scientifically if you were to conduct an awareness programme to highlight the values involved?
It is not appropriate to blame women for producing female children because scientifically it is the father who determines the sex of the baby.
The scientific explanation for the following is:
The chromosome pattern in human females is XX and human males are XY. Males are heterogametic and produce two types of gametes one carrying X and the other carrying Y. The females are homogametic and produce same type of gamete carrying X chromosome. The sex of the child depends on the sperm that fuses with the ovum. If the fertilizing sperm has an X chromosome, then the baby would be a female and if a sperm with Y chromosome fuses with the ovum, it will develop into a male child. Thus, males are responsible for determination of the sex of a child. So, we should not blame women for the birth of a female child and stop ill-treating them.
