A population of stone crabs is composed equally of three phenotypes: Dark brown (BB)
Medium brown (Bb)
Light brown (bb)

The crabs' color is controlled by incomplete dominance.
An introduced crab predator favors medium brown crabs, while avoiding the dark
brown and light brown crabs. Predict how this selection pressure will affect the
relative frequencies of the B and b alleles in future generations of crabs. Assume all
other selection pressures remain the same, and that there is no migration of crabs
into or out of the population.
