Genome comparison between species
WebIn general, the more DNA differences in homologous genes between two species, the more distantly the species are related. For instance, human and chimpanzee insulin genes are much more similar (about 98% identical) than human and chicken insulin genes (about 64% identical), reflecting that humans and chimpanzees are more closely related than ... WebTo compare different species, scientists cut the DNA of the species into small segments, separate the strands, and mix the DNA together. When the two species’ DNA bonds …
