When a red flowered pea plant was crossed with a white flowered pea plant, it was found that all plants in the F1generation carried only red flowers. If these plants are self crossed, i) Find the genotypic ratio that we can expect in F2 generation ii) What is the phenotype and genotype of F1 generation. Draw Punnett square for F2

The correct answer is -

i) genotype of F2 - 1:2:1 = dominant:heterozygous:recessive

ii) genotype of F1 - all heterozygous dominant

phenotype - all red

Explanation:

In the cross of red- flowered plant and white flowered plant the offspring produces red flowers that s only possible if the parent red flower plant has both alleles in dominant condition.

For the F1 the gametes will be R, R and r, r

from the Punnett square, we can see all the offspring are heterozygous (Rr) in genotype and red in phenotype

For F2 the gametes will be - R, r, and R, r

From the punnet square, the genotype we get is 1:2:1 = dominant:heterozygous:recessive

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

age range would be the answer
