Answer 2

The correct option regarding the fertilization of an egg by a sperm having an X chromosome is (a) A girl, as the unfertilized egg has one X chromosome.

• When the male gamete fertilizes the female gamete then zygote formation takes place and the process is known as fertilization.
• The male gamete is sperm and has 23 pairs of chromosomes while the female gamete is an egg and it also contains 23 pairs of chromosomes.
• Out of 23 pairs of chromosomes, one pair is the sex chromosome and 22 pairs of chromosomes are autosomes.
• The sex chromosome in males is X and Y and in females, it is X and X.
• During fertilization, either X or Y of pair of chromosomes fertilize with the X chromosome of the female.
• Male chromosomes decide the sex of a child because both the chromosomes of the female are the same i.e
• In the above example, X from sperm fertilizes the egg, which means the resulting offspring will have XX chromosomes. XX chromosome is the feature of a girl child while the XY chromosome is present in a boy.
