Question

How many eggs are released by a human ovary in a month? How many eggs do you think would have been released if the mother gave birth to identical twins? Would your answer change if the twins horn were fraternal?

Answer 1

i) Human ovary produces only one egg in a month.
 (ii) As the identical twins are monozygotic and are produced from two parts of same zygote so only one egg was released from the ovary. 
(iii) As the fraternal twins are dizygotic and are produced from two different zygotes which is possible only if two eggs are released from the ovaries in a month.

Answer 2

Answer:

A) ONLY ONE EGGS are released by a human ovary in a month.

B) Identical twins are the case of monozygotic state when twins are produced from the two parts of the Zygote. It means twins are produced from one egg in the ovary.

So ONLY ONE EGG would have been released if the mother gave birth to identical twins.

C) In the case of fraternal twins, the twin are produced from two eggs in the ovary. So that they are non-identical. In this case TWO EGGS are released if the mother gave birth to non-identical twins.
