How do fraternal twins form

Biology
1 answer:
Rzqust [24]3 years ago
3 0

Answer:

D. Two eggs are fertilized by two sperm.

Explanation:

Fraternal twins are dizygotic or multiviteline, that is, they are formed from two eggs and fertilized by two sperm.

In this case two oocytes are produced and both are fertilized, thus forming two embryos. They are almost always formed in different placentas and do not divide the amniotic sac.

Fraternal twins are not very similar to each other, may or may not have the same blood factor, and may or may not be of the same sex.

They are also popularly known as different twins. In fact they are two ordinary (not identical) brothers who had a coincident gestation.
