Every
living being has a definite number of chromosomes. In human beings there are 23
pairs of chromosome. Among them 22. pairs are similar in both male and female,
these are Autosomes . Members of the remaining pair of chromosome are different
in male and female. This pair of chromosome determines the sex of human beings.
As they determine the sex, so they are called X and y sex chromosome or sex determining
chromosome. One of the sex chromosomes is X chromosome and the other is Y
chromosome. If the sex chromosome pair is XY, the child will be male (son), and
if it is XX, the child will be female (daughter). In Drosophylla (a fly) also
XX indicate female and XY male. So in case of determining
the sex, the role of X and Y chromosome is vital.
