this is the act of grouping all the genes,genetic information, in any particular population especially from a specific species.

A large gene pool indicates extensive genetic diversity, which is associated with robust populations that can survive bouts of intense selection Meanwhile, low genetic diversity can cause reduced biological fitness  and an increased chance of extinction , although as explained by genetic drift new genetic variants, that may cause an increase in the fitness of organisms, are more likely to fix in the population if it is rather small.

When all individuals in a population are identical with regard to a particular phinotypical  trait, the population is said to be monomorphic. When the individuals show several variants of a particular trait they are said to be polymorphic

a genetic tree diagram is a is a branching diagram  or "tree" showing the inferred evolutionary  relationships among various biological species  or other entities—their phylogeny —based upon similarities and differences in their physical or genetic characteristics. The taxa joined together in the tree are implied to have descended from a common ancestor
