A) polyploidy
B) temporal segregation of breeding season
C) spatial segregation of mating sites
D) imposition of geographic barrier
Correct Answer: C
Solution :
There are some suggested case of sympatric populations evolving into separate species (eg, fish in the same lake and insects living in different species of food plants in the same habitat). This is called sympatric speciation, however, it is increasingly being discovered that the patches of habitats involved may be so, distant compared with the motility or dispersal of the organisms when mating that they are effectively micro-geographically isolated.
