Answer 2

Answer:There are 2types of twins

1.Monozygotic twins

2.Dizygotic twins

Explanation:1.Monozygotic twins= Monozygotic twins are formed from single embryo. During early period of embryonic development, cells of that embryo divided into two groups.

2.Dizygotic twins= Two oocytes are released from the ovary of women and both oocytes are fertilized by two separate sperms and thus two zygotes are formed. Two embryos are formed from those two zygotes and both of these embryos are separately implanted in the uterus and thus dizygotic twins are delivered after complete development.
