Which type of natural selection is described? individuals near the center of the curve (average individuals) have higher fitness and the bell curve becomes more narrow
Which type of natural selection is described? individuals at one end of the curve have higher fitness than individuals elsewhere in the curve and the range of phenotypes shifts in one direction
Which source genetic variation is described? a heritable change in genetic information
