the last one: artificial selection/genetic engineering
plant breeding is modifying the genetic composition of the plant - but this isn't cloning (which is specifically introducing a gene into a genome). but you are artificially selecting for the phenotype that you want.
the second one is literally genetic engineering - the gene would have been cloned first and then inserted or genetically engineered into the new plant cell (the cotton).
Which allele is expressed in the first-generation offspring of parents that have two different traits? a. the segregated allele b. the true-breeding allele c. the recessive allele d. the dominant allele
