Question asked by Filo student

(germ line or somatic) 23) In the laboratory, fruit flies (Drosophila) were artificially selected for the number of bristles on their bodies. One population (R) was selected for low numbers of bristles, a second population (S) for high numbers of bristles. After 35 generations (about 1 year's time), the two populations R and S were studied. What did researchers find? (4 pts) that the intemediate number of bristles caused the larger mumbers in population. B) What type of selection is this (The answer is not Artificial Selection)? (1 pts) Stabilizing -1
