Question

Infer why phylogenetic analysis based on genomes likely better reflects evolutionary relatedness over phylogenetic analysis using single gene

Answer 1

The phylogenetic analysis based on genome depicts better evolutionary relationship as Compared to the single gene. Because single gene can be mutated when exposure to radiation. Or there may be found spontaneous mutation in single gene. There mayel be the fact that there is change in single gene occurs due to natural selection. In this way, the single gene gives false result sometimes. When we consider single gene, then the distant species can be found as closely related ones. Thats why whole genome analysing is the better way for finding out the relatedness.
