how are twins born??? twins always identical or not identical?? Are twins always of same sex?? Please answer guys....if u know​

Answer 1

Answer:

twins can be born through 2 different types. They are not always identical or of same sex either.

Explanation:

To form identical (monozygotic) twins, one fertilised egg (ovum) splits and develops into two babies with exactly the same genetic information. These twins are always of the same sex. To form fraternal (dizygotic) twins, two eggs (ova) are fertilised by two sperm and produce two genetically unique children. This is when the children can be of two different sexes.
