Question

How do DNA help in defining evolutionary relationship? ​

Answer 1

Answer:

The similarities between the two organisms as well as the ancestral relationship can be determined using DNA sequences of different organisms. The arrangement of nucleotides in DNA defines the evolutionary relationships among the different organisms. Not only similarities but also differences helps to study evolution. Scientists separate strands of DNA from both species using heat, which breaks the bonds between the base pairs that link the two sides of the double helix. They then chop up the genetic information into small parts, mix up the genetic information from both, and watch how they recombine.
