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 born were fraternal?

An ovary releases an
egg every month. When two babies are produced in succession, they are
called twins. Generally, twins are produced from a single egg by the
separation of early blastomeres resulting from the first zygotic
cleavage. As a result, the young ones formed will have the same
genetic make- up and are thus, called identical twins.
If the twins born are
fraternal, then they would have developed from two separate eggs.
This happens when two eggs (one from each ovary) are released at the
same time and get fertilized by two separate sperms. Hence, the young
ones developed will have separate genes and are therefore, called
non-identical or fraternal twins.
