Identical twins are also known as

Options

A. Monozygotic twins
B. Dizygotic twins
C. Fraternal twins
D. Both B and C.

Answer

**Step-by-Step Solution:**

1. **Understanding Twin Types**: There are two main types of twins: identical (monozygotic) and fraternal (dizygotic).

2. **Identical Twins Definition**: Identical twins, also known as monozygotic twins, develop from a single fertilized egg (zygote) that splits into two embryos. This means they share the same genetic material.

3. **Fraternal Twins Definition**: Fraternal twins, also known as dizygotic twins, occur when two separate eggs are fertilized by two different sperm cells. This results in two genetically unique embryos.

4. **Conclusion**: Since identical twins come from one zygote, they are referred to as monozygotic twins. Therefore, the correct answer to the question is option A: monozygotic twins.

**Final Answer**: Identical twins are also known as monozygotic twins.
