A zygote which has an X-chromosome inherited from the father will develop into a
(a) boy
(b) girl
(c) X- chromosome does not determine the sex of a child
(d) either boy or girl
Answer:(b)
Solution:
In humans, sex of the child is determined by chromosome inherited by the father.
If the zygote inherits X chromosome, the zygote will develop into a female.
If the zygote inherits Y chromosome, the zygote will develop into a male.
Therefore, option (b) is correct.
