Final answer:
The correct match between description with its term is as follows:
- Fraternal Twins: dizygotic twins & two sperms and two eggs
- Identical Twins: monozygotic twins & one sperm and one egg
Step-by-step explanation:
1. Fraternal Twins: Fraternal twins, also known as dizygotic twins, occur when two separate eggs are fertilized by two different sperms. Each twin develops from a different fertilized egg and therefore shares about 50% of their genetic material. Fraternal twins can be of the same or different genders and may or may not resemble each other closely.
2. Identical Twins: Identical twins, also known as monozygotic twins, occur when a single fertilized egg splits into two embryos. As a result, both twins share the exact same genetic material and are of the same gender. Identical twins are often highly similar in appearance and have nearly identical DNA profiles.
In summary, fraternal twins are dizygotic twins that develop from two separate eggs fertilized by two different sperms, while identical twins are monozygotic twins that develop from a single fertilized egg that splits into two embryos.
Your question is incomplete, but most probably the full question was:
Match each description with either fraternal or identical twins.
- Fraternal Twins
- Identical Twins
- monozygotic twins & one sperm and one egg
- dizygotic twins & two sperms and two gets
