Woman are often blamed for bearing daughters. As a student with knowledge in science how will you
explain it to your fellow students that the sex of the child is not determined by mother’s genetic
contribution?
Answers
women do not have any role in deciding the sex of their child. It is actually the male whose sperm chromosome decides the fate of the sex of the child.
Females have 23 pairs of chromosomes, 22 + XX (sex chromosome) and males have 23 pairs of chromosomes as well 22 + XY (sex Chromosome). While fertilization ova will be carrying one X chromosome while sperm would either be carrying X or Y chromosome. So if ova having X chromosome fertilizes with sperm having X chromosome, the child will be Girl (XX) and if ova having X chromosome fertilizes with sperm having a Y chromosome, the child will be a boy (XY). Thus mothers are wrongly blamed.
In humans, this XX, XY type of determination occurs to determine the sex of children.
