Answer 1

Sex determination in Human being

(1) The statement Gender of child is determined by the male partner of couple is true.

(2) It is clearly seen from the diagram that there are two types of sperms produced by males. One sperm has a X chromosome while the other has a Y chromosome, apart from autosomes. The mother on the other hand has all X bearing oocytes.

Thus the sperm that fertilizes the oocyte decides the sex of the child.

(3) If X bearing sperm fertilizes the oocyte, daughter is born and when Y bearing sperm fertilizes the oocyte, son is born.

(4) Thus father or male partner is responsible for the determination of the sex.
