Use a punnett square to explain how a dominant allele masks the presence of a recessive allele

In this punnett square the letter G represents the dominant allele, for example yellow. The letter g represents the green recessive allele. We can observe that when crossing between an organism with a homozygous dominant genotype GG and a homozygous recessive green genotype organism, all offspring that have a Gg genotype will be yellow because the G allele is dominant and masks the recessive allele g

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
