In snapdragons red flower color (C R ) is incompletely dominant to white flower color (C W ) and the heterozygote has pink flowers. Green leaves (G) are dominant to purple leaves (g). A pink flowered, purple leafed snapdragon is crossed with a pink flowered snapdragon heterozygous for leaf color. 1. What proportion of the progeny should be pink flowered, purple leaved plants?

i think i can answer even without the example. over time with environmental changes, sometimes a group of animals will adapt to better survive. take a moth for example. if the trees the moths use to camouflage themselves from predators, started to die or change colors themselves, the moths may, overtime of course, change color too. its just adapting to its surroundings. hope i was of any : )
