Question

Tracking the evolutionary history of individual genes in a group of species can reveal which genes have remained in a genome for a long time and which genes have been horizontally transferred between species.

(a) True

(b) False

This question was addressed to me by my school teacher while I was bunking the class.

I'm obligated to ask this question of Reliability of Phylogenetic Predictions topic in section Phylogenetic Tree Construction Methods and Programs of Bioinformatics

Answer 1

Correct option is (a) True

Easiest explanation: Thus, phylogenetic analysis can also contribute to an understanding of genome evolution. Or e.g. from a phylogenetic analysis of the protein family, the plant gene most closely related to the yeast gene and therefore most likely to have the same function can be determined.
