And male and female reproductive systems are responsible for breeding.
The male. He carries an X and Y chromosome. If he gives an X, the fetus is female. If he gives a Y, the fetus is male.

The sex chromosomes, X and Y. Having two X's makes you female, and an X and Y makes you a male.
Yes, both male and female jackrabbits exist. Female jackrabbits are responsible for giving birth to and caring for their young. Both male and female jackrabbits play a role in the reproduction and survival of the species.
its actually the male who recognises the sex of a child bc the male has either has an x chromosome or a y while the female always has an x chromosome. so if an x from the male fertilizes the egg in the female, a female child would be born and if a y from a male fertilizes the egg then a male child would be born. All this scientific truth is contrary to what is believed in many primitive and ignorant societies and cultures of the world where they think that its the woman who is responsible for the birth of a female child.
