Question

The mother is not responsible for determining the sex of baby.Give reasons​

Answer 1

Since long it has been considered that females are responsible for determining the sex of the developing foetus. However, it is evident that human females are homogametic. They produce the same types of ova, each having the X chromosome. The human males are heterogametic. They have XY as sex chromosomes and so they produce 50% sperms with X chromosome and another 50% with a Y chromosome. If the sperm having X chromosome fuses with the ovum, a female foetus will be formed. If the sperm having Y chromosome fuses with an ovum, a male foetus is formed. So, the deciding factor is contributed by the males and the sex of the foetus depends on the probability. Hence, we all must take efforts to stop female foeticide and mother is not responsible for a girl child.

Answer 2

Answer:

"You just can't foresee it in women," Mr. Gellatly adds. The sex of a kid is determined by whether a man's sperm carries an X or Y chromosome. A newborn girl (XX) is born when an X chromosome joins with the mother's X chromosome, while a boy is born when a Y chromosome fuses with the mother's (XY)

Explanation

Females have long been thought to be responsible for deciding the sex of the growing embryo. Human females, on the other hand, are clearly homogametic. They both have the X chromosome and generate the same sorts of oocytes. Males in the human species are heterogametic. Because they have XY chromosomes as sex chromosomes, they generate 50% sperm with the X chromosome and 50% with the Y chromosome. A female baby is created when sperm bearing the X chromosome unite with the ovum. A male baby is generated when sperm carrying the Y chromosome unites with an ovum. As a result, men are the decisive factor, and the sex of the embryo is determined by chance. As a result, we must all work together to put an end to female genital mutilation.

conclusion

The presence of sex chromosomes in the cells determines the gender of a baby. The infant will be a female if the sex chromosomes are in the XX pair. If the child's sex chromosomes are XY, he will be a boy.
