In general, the frequency with which crossing over occurs between two linked genes depends on what?

The distance or how the genes lies far apart on the chromosome.

Explanation:

Crossing over may be defined as the process of exchange of the genetic material of the two non-sister chromatids. The process of crossing over occurs during the process of meiosis.

The frequency of the crossing over generally depends upon the distance between the genes present on the chromosome. Linked genes are present on the same chromosome.

answer; atp and nadph;

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
