Which factor do biologists calculate when they determine whether a population is in hardy-weinberg equilibrium?
mutation rate
genotype frequencies
number of phenotypes
rate of migration

The correct answer is-

genotype frequencies.

Hardy-Weinberg equilibrium is a condition according to which frequency of gene variant in the population of sexually reproducing individuals remains constant over generations ( that is it does not change from one generation to another generation).

There is an equation for the Hardy Weinberg law, which helps in determining the genotypes ( such as frequency of homozygous dominant, heterozygous domiant, and homozygous recessive genotypes). The equation is-

Where p² represents the homozygous dominant, 2pq represents heterozygous domiant, and q² for homozygous recessive genotypes.

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
