Science word for y and x?
x chromosone and y chromosone
Does the mother or the father determine the sex of the offspring?
No, it is the male. The female eggs or ovum only have the x chromosone which develop into a female. The sperm have either an x chromosone or a y chromosone which carries the male sex determination. It is by chance and timing which one fertilized the egg first. If it is a x chrromosone then the offspring is a female. If the y chromosone fertilized the egg, then chemical changes occur resulting in a male fetus. No, it is the male. The female eggs or ovum only have the x chromosone which develop into a female.
