In a monohybrid cross, if the gene for tall (t) plants was incompletely dominant over the gene for short (t) plants, what would be the predicted result of crossing two intermediate (tt) parent plants? (hint: you may want to complete a punnett square.)
1) 25 percent tall, 50 percent intermediate, 25 percent short
2)50 percent tall, 25 percent intermediate, 25 percent short
3)100 percent intermediate
4)25 percent tall, 75 percent intermediate

Option 1

Explanation:

It is given that gene for tall (T) is dominant over gene for short i.e t

Thus , if T and t are present together in an allele pair then the individual would be an intermediate species.

Genotype of both the parents - Tt

Tt * Tt

TT, Tt, tt, Tt

Thus out of four offspring one is tall. Thus probability of tall species is 25%

out of four offspring one is short. Thus probability of short species is 25%

out of four offspring two are intermediate. Thus probability of intermediate species is 50%

Hence, option  1 is correct

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

the correct answer is:

a population changes in response to a change in the environment.
