Question

female are not responsible for the sex of the baby explain the statement with suitable Cross
​

Answer 1

Answer:

This can be justified as follows -

1 Male will have 2 sex chromosomes ie XY and female will have XX as their sex chromosomes.

2 Thus male can donate either X or Y and female will donate only X at the time of gamete formation.

3 Now if, X chromosome is given by male and X from female - it will form female and if male donates Y chromosome and female gives X then it will be male (as XY is male and XX is female).

4 Thus we can say that sex determining chromosome is given by males hence they are responsible for sex of the children.
