Question

The biological concept of species in addition to morphology takes into considerationA. ecology
B. geneticsC. cytology
D. all of these

Answer 1

The biological species concept defines species as “species are groups of interbreeding natural populations that are reproductively isolated from other such groups."

When two organisms breed within a species, their genes pass into their combined offspring. As this process is repeated, the genes of different organisms are constantly shuffled around the species gene pool.

The shared gene pool gives the species its identity. Interbreeding between species is prevented by isolating mechanisms.
