Question

A gene phylogeny only describes the evolution of a particular gene or encoded protein.

(a) True

(b) False

The question was posed to me in homework.

My query is from Gene Phylogeny Versus Species Phylogeny in portion Molecular Phylogenetics of Bioinformatics

Answer 1

The correct answer is:

(a) True

A gene phylogeny specifically describes the evolutionary history of a particular gene or the protein it encodes. This is different from a species phylogeny, which represents the evolutionary relationships among species or organisms. Gene phylogenies can differ from species phylogenies due to events like gene duplication, horizontal gene transfer, or other evolutionary processes that affect individual genes independently of the species they are part of.
