Question

Sequences are now available for both the human and the chimpanzee genomes. Outline how you would analyze homologous genes in the two spe- cies to determine which of the observed sequence differences result from drift and which result from selection?

Answer 1

To analyze homologous genes in the human and chimpanzee genomes, you would need to compare the DNA sequences of the genes in both species. By using computational tools like BLAST, you can determine the percentage of sequence identity or homology to estimate evolutionary distance and identify differences resulting from genetic drift or natural selection.

Step-by-step explanation:

To analyze homologous genes in the human and chimpanzee genomes, you would need to compare the DNA sequences of the genes in both species. One way to do this is by using computational tools like BLAST, which allows you to align and analyze sequences. By comparing the sequences, you can determine the percentage of sequence identity or homology, which can give you an estimate of the evolutionary distance between the two species. Differences in sequence can result from genetic drift or natural selection.
