PLEASE HELP I DONT UNDERSTAND How does having genes on many chromosomes, rather than on just one chromosome, increase genetic variation among offspring?

Genetic variation is increased by meiosis

Because of recombination and independent assortment in meiosis, each gamete contains a different set of DNA. ... A gamete will end up with 23 chromosomes after meiosis, but independent assortment means that each gamete will have 1 of many different combinations of chromosomes

Explanation:

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
