The sex of a new born child is a matter of chance and none of the parents may be considered responsible for it justify this statement with the help of a flow chart showing sex determ ination in human beings
Answers
Answer:
In human beings, the females have two X chromosomes and the males have one X and one Y chromosome. Therefore, the females are XX and the males are XY.
At the time of mating, large number of sperms are ejaculated from the male reproductive organ (penis), into the female reproductive organ i.e. vagina. They travel towards the fallopian tubes, where only one sperm meets with the egg.
The process of fusion of the sperm and ovum is called fertilization. The sperm has either X or Y chromosome and egg has only X chromosome. So, if sperm carrying Y chromosome fuses with egg the newly born child will be male and if sperm carrying X chromosome fuses with the egg the newly born child will be female. There is an equal chance of fusion of either X or Y chromosome with the egg so we can say that the sex of new born child is a matter of chance and none of the parent is responsible for it.
