Answer 13

Biological: actually/potentially interbreeding natural population that are reproductively isolated from other such groups
Cohesion: inclusive group of organisms having potential for genetic/demographic exchangeability
Evolutionary: single lineage of ancestor descendent population that maintains its ID from other such lineages and has its own evolutionary tendencies and historical fate.
Phylogenetic: smallest aggregation of population (sex) or lineages (asexual) diagnosable by a unique combo of character states in comparable individuals
Recognition: most inclusive population of individual biparental
organisms that share a common fertilization system.
