Question

Identify the incorrect statement about identical twins.
i) developed from a single zygote ii) always of the same sex
iii) look alike in many aspects iv) differ in their blood groups

Answer 1

The incorrect statement on the facts about the identical twins is - iv) differ in their blood groups.

Monozygotic twins are identical because they are developed from the same zygote.

The zygote later splits and results in the formation of two embryos.

They can be referred as dizygotic fraternal for which the twin develops from a separate egg.

Each egg gets fertilized by the sperm cell.

The twins look identical as the source of the twins is same.
