Adorable and hilarious twins will make you smile… VIDEO

Twins’ unique relationship allows researchers to investigate differences in genetic and environmental influences on physical and mental health, as well as traits and behaviors. We can learn a lot about diseases, disorders, and human nature in general by studying twins. Twin studies can help answer questions about many aspects of human nature.

Approximately three or four newborns out of every 1,000 are identical twins. There are various types of twins, the most common of which are identical and fraternal. Identical twins, also known as monozygotic twins, are born from the same fertilized egg that divides into two. These identical twins are of the same sexes and share the same genes.

Identical twins, also known as paternal twins, exhibit a high level of genetic influence on human development. Fraternal or dizygotic twins are formed when two different eggs are fertilized by different spermatozoa; they usually share roughly half of their genes. As a result, fraternal twins are similar to typical siblings.
