Horizontal gene transfer is a potential confounding factor in inferring phylogenetic trees based on the sequence of one gene. For example, given two distantly related bacteria that have exchanged a gene a phylogenetic tree including those species will show them to be closely related because that gene is the same even though most other genes are dissimilar. For this reason, it is often ideal to use other information to infer robust phylogenies such as the presence or absence of ge… WebJul 17, 2015 · Horizontal gene transfer (HGT) is the sharing of genetic material between organisms that are not in a parent–offspring relationship. ...
