Question

who are twins ? short answers please​

Answer 1

Answer:

Twins are two offspring produced by the same pregnancy. Twins can be either monozygotic ('identical'), meaning that they develop from one zygote, which splits and forms two embryos, or dizygotic ('non-identical' or 'fraternal'), meaning that each twin develops from a separate egg and each egg is fertilized by its own sperm cell.

Answer 2

• Identical twins are born when a single fertilized egg cells splits into two .
• Fraternal twins are born when two egg cells are fertilized by two sperm cells at the same time .
