∙ 13y agoIdentical Twins
Sometimes, after fertilisation, the fertilised ovum splits and divides into two balls of cells. Twins formed in this way are identical. They develop from the same ovum.
Non-identical Twins
Sometimes a woman's ovaries release two or more ova at the same time. If they all become fertilised, they all develop into babies. Twins formed in this way are non-identical. They develop from different ova fertilised by different sperms.

∙ 11y agoThere are two two kinds of twins.
Gametic twins - two sperms fuse with two eggs to form gametic twins.
In the case of gametic twins, the twins are not identicaland infact there is a chance for one male and another female.
Zygotic twins - zygote forms after fertilisation (Fusion of sperm and egg). The zygote divides in to two cell and these two new cells develops in to twins.
In the case of zygotic twins, the babies are identicaland both the twins will be males or females.
