Question

A way to discern lateral gene transfer is through phylogenetic analysis, referred to as an ‘among-genome’ approach, which can be used to discover __________

(a) recent lateral gene transfer events but almost negligible ancient events

(b) recent lateral gene transfer events

(c) ancient lateral gene transfer events

(d) both recent and ancient lateral gene transfer events

I got this question in unit test.

My question is taken from Comparative Genomics in chapter Genome Mapping, Assembly and Comparison of Bioinformatics

Answer 1

Correct option is (d) both recent and ancient lateral gene transfer events

The best I can explain: Abnormal groupings in phylogenetic trees are often interpreted as the possibility of lateral gene transfer events. There are some basic tools for identifying genomic regions that may be a result of lateral gene transfer events using the within-genome approach, namely, ACT, Swaap.
