Answer:
In humans, 23 pairs of chromosomes are there. Out of which 22 pairs are known as autosomes. 23rd pair of chromosome is known as sex chromosome. In females, all 23 pairs of chromosomes are 'xx' but in males, 23rd pair is 'xy'. If the x chromosome of female fertilisis with y chromosome of male, then male child is produced and if it fertilisis with x chromosome of male then female child is produced.
