Question

4.) How were the twins different?
​

Answer 1

Explanation:

There are two types of twins – identical (monozygotic) and fraternal (dizygotic). ... This differs from fraternal twins, where two eggs (ova) are fertilised by two sperm and produce two genetically unique children, who are no more alike than individual siblings born at different times.

Answer 2

1. There are two types of twins – firstly identical also called Monozygotic.

and the second type is fraternal also called Dizygotic.

2. This differs from fraternal twins, where two eggs (ova) are fertilised by two sperm and produce two genetically unique children, who are no more alike than individual siblings born at different times.

3. Identical means Monozygotic twins share all of their genes and are always of the same sex.

4. Whereas Dizygotic twins result from the fertilization of two separate eggs during the same pregnancy.

5. They share half of their genes, just like any other siblings. They can be same or of different sexes.
