Do twins, that split from the same egg (is this maternal?) have the exact same DNA?
Twins are considered to have the same DNA when they are conceived from a single fertilized egg, also known as identical twins. This means that they share 100% of their genetic material, making them genetically identical.
No, fraternal twins are conceived from two separate eggs fertilized by two different sperm. This means that they share approximately 50% of their genetic material, just like any other siblings.
While identical twins have the same DNA, they can still have different physical traits due to epigenetics. Epigenetics is the study of how environmental factors can influence gene expression, meaning that even though twins have the same DNA, their physical traits can be influenced by their unique experiences and environments.
Technically, no. Identical twins have the exact same DNA sequence. However, as they go through life, small mutations may occur in their DNA, which can lead to slight differences in their genetic makeup. These mutations are not significant enough to change their physical appearance or health.
There is no scientific evidence to suggest that twins have a stronger maternal connection than other siblings. While they may have a unique bond due to sharing a womb and being born at the same time, the strength of their connection is dependent on individual experiences and relationships with their mother, just like any other sibling.
