Two frog populatioes of the same species, living in two neighboring lakes sing slightly different courtship songs. now make a different assumption: that courtship song differences have a genetic basis and that fitness differences are linked to the song tynes i. c. cach population has highest fitness in its home pond now predict what likely happens to the songs of the two frog populations after increased irrigation makes the land between the two lakes wetter, and therefore leads to increased connectedness between the two lakes

a) there is no change in the frog courtship songs of the two lakes
b) female preferences for males from her own population will decrease
c) the songs will become more similar to each other
d) the songs will become more differeet from each other.

The songs will become more similar to each other.

Explanation:

Speciation may be defined as the process of formation of new species by the external or internal force. Two main types of speciation are allopatric speciation and sympatric speciation.

Two frog population belongs to the same species that lives two neighboring lakes. The irrigation makes the pond wetter and connect the two species. The  songs of the two species tends to be more similar in both species s singing is genetic basis and allows the mating between two species.

Thus, the correct answer is option (c).

increase soil erosion                                             reduce soil erosion

cattle grazing                                                         hydroseeding

deforestation                                                         contour plowing

                                                                                planting vegetation

plant roots basically hold the top soil

together and stop soil erosion because

in such situation top soil is not removed

during flood but cattle grazing causes

soil erosion because cattle consume the

grasses and herbs and top soil is exposed.

same situation occurs because of

deforestation, the trees and plants are cut

down to expose top soil which causes soil

erosion
