Gene trees can be used to estimate times of coalescence for

A) only closely related alleles in a population.
B) only distantly related alleles in a population.
C) all populations where a single individual had the ancestral allele.
D) all possible pairwise combinations of different alleles in a population.

Gene Trees

Diagrams that show the inferred evolutionary relationships among various genes derived from different species.

Coalescence Times

A concept in molecular evolution and population genetics referring to the point in time where genetic variants shared among individuals can be traced back to a common ancestor.

Ancestral Allele

The genetic variant of a gene that is believed to have existed in the common ancestor of a species or group of species.
