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
