उत्तर
Identical Twins (Produced from one egg): Sometimes a single fertilized egg may get split and separated into two parts during its early stages of cell division. Each of these two split parts then behaves like an independent egg and produces one complete individual each. These are called Identical twins.
Fraternal Twins: Sometimes, two eggs are released from ovaries at a time and both may get fertilized to produce two individuals. These are called fraternal twins.
