Question

what are transgenic organisms. is it correct to hold the spermatozoa of the father responsible for deciding the sex of the foetus ? explain briefly

Answer 1

Its absolutely not obvious that the egg should decide the sex of the baby just because the mother bears the baby. To decide the sex of the baby u have to look at the chromosomes of males and females. All human beings have 2 types of chromosomes - the autosomes and the sex chromosomes. The sex chromosomes bear the genes for deciding sex of baby. There are 2 types of sex chromosomes - X and Y. All females (normal) have 2 XX chromosomes while the males (normal) have 1X and 1Y chromosome. Now as we know that during gamete formation only one the 2 chromosomes of the pair are passed to the gamete, all the eggs would have only X chromosome (of the sex chromosomes) while the sperms can have either X or Y. When a sperm bearing X chromosome fertilizes the egg, the resultant zygote would be a female as it has XX chromosomes. On the other hand when a sperm bearing Y chromosome fertilizes the egg, the zygote would develop into a male as it has XY chromosomes. It is clear that it is the father who decides the sex of the baby, not the mother, due to its heterozygous nature.

Answer 2

well yes father is responsible for deciding the sex of the child because as mother can only produce x chromosome and father can both so it depends on father whether it will be a boy or girl
because XX makes girl And XY makes boy
