How is sex of the baby determined? Is the mother responsible for the sex of her baby? Justify your answer.
Answers
Answer:
Men determine the sex of a baby depending on whether their sperm is carrying an X or Y chromosome. An X chromosome combines with the mother's X chromosome to make a baby girl (XX) and a Y chromosome will combine with the mother's to make a boy
Answer:
Hey mate!
The sex chromosomes determine the sex of a person.
The sex of a child depends on what happens at fertilisation:
(a) If a sperm carrying X chromosome fertilises an ovum (or egg) which carries X chromosome, then the child born will be a girl. This is because the child will have XX combination of sex chromosomes.
(b) If a sperm carrying Y chromosome fertilises an ovum (or egg) which carries X chromosome, then the child born will be a boy. This is because the child will have XY combination of sex chromosomes.
In short, the sex of a baby mainly depends on the father not her mother.
