Question

Why most of the twins are similar?

Answer 1

Twins:

1. Most of the twins are similar because they share identical genes.
2. Twins may be identical or non-identical.
3. Identical twins arise when "one" egg is fertilized and the resulting embryo then splits to become two embryos, they contain the same genetic information and so develop in the same way.
4. They share same blood type.
5. Therefore, most twins are similar.
