The observation that SNPs account for most of the differences in the coding regions between the human and chimpanzee genomes suggests that ____.

Question

Quizplus · Accepted Answer

SNPs are single nucleotide polymorphisms, which are variations in a single nucleotide. If these variations occur in genes that code for proteins, they can lead to differences in the amino acid sequence of the resulting protein. Therefore, small changes in DNA sequence can lead to big differences in the phenotype of the organism. The fact that SNPs account for most of the differences in the coding regions between the human and chimpanzee genomes indicates that these small changes have played a significant role in the evolution of these two species.
