Answer #1

SEX DETERMINATION OF A BABY:-
           - When a baby is conceived, a chromosome from the sperm cell, either X or Y, fuses with the X chromosome in the egg cell determining, the baby will be
           - female (XX) or

    because of the presence of the sex determining region of the Y chromosome, also known as the SRYgene.

In humans the sex of an individual is determined by the sex chromosomes that they inherit. All individuals carry two sex chromosomes, but males carry a so-called X and a Y chromosome (and are thus called XY) whereas females carry two X chromosomes (and are thus called XX). When a male and female produce an offspring, each gives the offspring one of its sex chromosomes, chosen with equal probability. Thus, a child always inherits an X chromosome from its mother...
