Tomatoes carry a gene called fw2.2 that encodes a protein made during early fruit development?the job of which is to repress cell division
Additionally, researchers have identified a second gene called fas that controls the number of compartments in the mature fruit. Artificial selection leading to the production of very large tomatoes has apparently capitalized on ________. A) alleles associated with low production of the repressor protein and an increase in the number of fruit compartments B) alleles associated with high production of the repressor protein and an increase in the number of fruit compartments C) alleles associated with low production of the repressor protein and a decrease in the number of fruit compartments D) alleles associated with high production of the repressor protein and a decrease in the number of fruit compartments
Discuss how two of the following alter allele frequencies in populations: nonrandom mating, genetic
drift, gene flow, and natural selection What will be an ideal response?
