In many cultivated plants (such as oranges, bananas, and potatoes), favorable characteristics often are created by careful genetic crosses. of the following, which would be the best way to maintain the traits of a new variety with favorable characteristics
a) selfing individuals of this new variety (i. e, crossing the offspring of one parental plant)
b) artificially pollinating wild varieties with pollen from the new variety
c) crossing the new variety with a variety that was homozygous recessive for all traits of concern.
d) vegetative reproduction of the new variety

C

Explanation:crossing the new variety with homozygous recessive ones means there is high chance of these being dominant over the trait that Re of concern

answer: oof wait

explanation:

sheep is a herbivore animal whereas grasshopper belongs to the class chordates but both of them feed on greens.  

if grasshopper and sheep feeding on a pasture land, i do not think both of them will have any impact on each other. however, the number of the species can make difference. since sheep feed on greens, there is a possibility there left no pasture land for the grasshoppers or they may get extinct.
