Question

Do twins have the same DNA and fingerprints?

Answer 1

DNA Fingerprinting:

1. DNA is a polymer composed of two polynucleotide chains that coil around each other to create a double helix and contains the genetic instructions for the development, function, growth, and reproduction of all known species.
2. DNA fingerprinting is a way of establishing an individual's identification based on the nucleotide sequences of particular portions of human DNA that are unique to each person.
3. Twins are genetically similar since they are created from a single fertilized egg that splits into two. They don't, however, share the same fingerprints.
4. A twin is one of two children born at the same time to the same mother.
5. Twin studies enable the disentanglement of the characteristic of interest's shared genetic and environmental components. Researchers can assess the amount of a trait's variance owing to genetic variation against the proportion due to a shared or unshared environment.
6. Thus, Twins share DNA but not fingerprints.
