Statements regarding twins is correct

Twins can be classified into two main types: identical (monozygotic) twins, who originate from a single fertilized egg that splits into two, and fraternal (dizygotic) twins, who develop from two separate eggs fertilized at the same time. Identical twins share 100% of their genetic material, while fraternal twins share about 50%, similar to regular siblings. Twins often have unique experiences and can exhibit similar traits, but their individual personalities and health outcomes can vary significantly. Additionally, the likelihood of having twins can be influenced by genetic factors, maternal age, and certain fertility treatments.
