In a diploid species of plant, the genes for plant height and fruit shape are syntenic and separated by 18mu. Allele D produces tall plants and is dominant to d for short plants, and allele R produces round fruit and is dominant to r for oval fruit. a. Identify the gametes for a plant with the genotype DR/dr, label parental and recombinants and give the frequency of each gamete type.
b. Give the same information for a plant with genotype Dr/dR

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
