Question

A phylogenetic tree can be used to examine:  

Select one:

Genetic relatedness between family members

All of these

Patterns of local adaptation

Gene flow and genetic diversity of species

Timing of genetic divergence between species

Answer 1

Ans) The correct answer is "B" i.e all of these

(Phylogenetic tree can be used for the determination of the common ancestors of the newly diverged species or organisms and by this information we can also find out in which characters they are diverged. Likewise, the timing of genetic divergence between species can also be found out. Recently diverged species would be latest and the oldest common ancester will be the oldest one according to time. Genetic relatedness can also be found out.If the two species share a common ancestor, it means that these two species are closely related than the other species which are derived from other ancester. Genetic diversity of the species can also be determined with the help of bioinformatic tools like performing multiple sequence alignment (MSA) and then contructing phylogenetic tree with program like Phylip).
