प्रश्न
Sketch and label human female reproductive system.
Is the woman responsible for sex-determination of child? Justify your answer.
उत्तर
Woman is not responsible for sex-determination. Man produces two types of sperms as 22+X or 22+Y, whereas woman produces only 22+X types of ova. Female embryo is produced by union of 22+X sperm and 22+X ovum. Male embryo is produced by union of 22+Y sperm and 22+X ovum. Thus, sex of the embryo depends upon sperms of man.
