In biology, various symbols were used to enhance understanding of human genetics out of which only [xx] and [xy] nearly gained a universal acceptance. It is a male parent, because there is [xy] inside the parent cell, but it is a female parent, because there is [xx] inside the parent cell. Our biologists told us that the chances of conceiving a female child is always homogeneous [x/x], likewise the chances of conceiving a male child is always heterogeneous [x/y ]. This is what constitutes the basic trend in human reproduction.
