The belief that the mother is completely responsible for the sex of the child is wrong because the child
(a) gets sex chromosome only from the mother.
(b) develops in the body of the mother.
(c) gets one sex chromosome from the mother and the other from the father.
(d) gets sex chromosome only from the father
Answer:
Answer is (c) gets one sex chromosome from the mother and the other from the father.
Explanation:
Mother has XX in their 23rd chromosome set. Mather always donates X to the offspring. Father has XY chromosome on the 23rd set. If the father donates X child will be female. If Father donates Y then the child will be male.
Hence it is the father who is responsible for the sex of the child.
