Question

Species occurring in different geographical area are called as

(a) sympatric

(b) allopatric

(c) sibling

(d) neopatric.

Answer 1

The populations of species which are seperated by physical barrier that may be due to river for animals that can not swim. The genotype propertion in each population is independently change the other. Hence the species occuring in different geographical area are called allopatric.

Sympatric species which live in the same area but are prevented from successful reproductive isolation mechanism.

Whereas sympatric speciation occurs due without physical barrier to gene flow. It's more common in plants.

Hence option (b) is correct.
