in 1917 the biologist thomas hunt morgan conducted studies in which he kept some caterpillars in the dark and placed some others under red, green, or blue lights. exposure to red light produced butterflies with brightly colored wings. exposure to green light resulted in dark-colored wings. exposure to blue light or no light resulted in pale-colored wings. what was the most likely conclusion of morgan’s research?

many plants naturally reproduce this way, but it can also be induced artificially. horticulturalists have developed asexual propagation techniques that use vegetative plant parts to replicate plants. success rates and difficulty of propagation vary greatly. monocotyledons typically lack a vascular cambium and therefore are harder to propagate.
