Question

9) Who is responsible for determination of a child
mother on
father​

Answer 1

Answer:

Father is responsible for the sex of the child

Explanation:

"The father is responsible for the sex of a child, not the mother." This statement is completely justified and can be proved as follows: A male has XY chromosomes and a female has XX chromosomes.

1. If a sperm carrying X chromosome from male gets combined with the X chromosome from female, then the combination will be XX and child will be a baby girl.

2. If a sperm carrying Y chromosome from male gets combined with the X chromosome from female, then the combination will be XY, and the child will be a baby boy.
