A population of small fish lives in a lake with a sandy bottom. the major predator of these fish is a wading bird that hunts by sight. most of the fish are light sandy brown, but about 10% are mottled. the color pattern is heritable. a construction company dumps a load of gravel in the bottom of the lake, giving it a mottled appearance. which of these statements presents the most accurate prediction assuming they don't just all die due to severe habitat pollution and food chain disruption?
