Scientists believe that there are three genes that contribute to skin color in humans. Which of these best describes the inheritance pattern of skin color?
multiple allele in which offspring receive three alleles from each parent
multiple allele in which offspring receive three alleles from only one parent
polygenic in which offspring receive three alleles from each parent
polygenic in which offspring receive three alleles from only one parent .

biology is the study of life. it is the study of living organism.

not sure if this what   you'r looking for would be percent composition

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).
