The rocks at the bottom of a stream are either black or white. Snails that live on these rocks are a range of color from solid black to gray to solid white. A local fish loves to munch on these snails, but it can’t see the solid black or solid white snails when the snails are on matching rocks. Gray does not blend into either rock color and is much easier to see. What type of selection will most likely occur? Group of answer choices

Stabilizing selection

Directional Selection

Disruptive Selection

Sexual Selection

Selective Breeding

Turtle hatchling survivorship rate is low in many turtle species due to predation. amanda researched the predatory rate on a species of turtle eggs in the red river. the eggs were harvested from trapped turtles and the egg's cloaca film (reproductive discharge) was either washed off or left on once gathered. research suggests that predators use the female's cloaca scent to locate the eggs. the eggs were only handled when wearing gloves and then reburied along islands where the turtles were trapped. the nests were monitored by cameras and manually on foot and data on nest predation were recorded. a. based on the experimental design, what is the dependent variable? b. based on the experimental design, what is the independent variable? c. based on the experimental design, what is the control?

All individuals have two alleles for a given trait. according to mendel's these alleles are passed down one each from both mother and father.
