Reproductive isolation in sympatric speciation develops without a
1 Geographic barrier
2 Barrier to gene flow
3 Change in chromosome number
4 Barrier to mating
Explanation:
In sympatric speciation, groups from the same ancestral population evolve into separate species without any geographical separation. Sympatric speciation occurs when there are no physical barriers preventing any members of a species from mating with another and all members are in close proximity to one another.

The finch species of Galapagos Islands are grouped according to their food sources. Which of the following is not a finch food?
1 Seeds
2 Carrion
3 Insects
4 Tree buds
Explanation:
Darwin finches show adaptive radiation. This radiation occurred in response to various food resources available. These finches feed on insects. Tree buds, seeds, cactus etc. Carrion are dead bodies and no finches feed on them.
