In a population of birds brightly colored males, and very dull, male survive best which type of selection is this and what is most likely true about the proposition of males of intermediate coloring
This is an example of directional selection, where individuals at one extreme of a trait are favored over others. In this case, brightly colored males are being favored over very dull males.
It is likely that males of intermediate coloring are at a disadvantage in this population. They are not as well camouflaged as the very dull males, and they do not stand out as much as the brightly colored males. Therefore, they may have a harder time surviving and reproducing compared to males at the extremes of the color spectrum.
