Sympatric speciation is speciation that occurs when two groups of the same species live in the same geographic location, but they evolve differently until they can no … Suppose there is a population of rabbits. The colour of the rabbits is governed by two incompletely dominant traits: black fur, represented by "B", and white fur, represented by "b". A rabbit in this population with a genotype of "BB" would have a phenotype of black fur, a genotype of "Bb" would have grey fur (a display of both black and white), and a genotype of "bb" would have white fur. If this population of rabbits occurred in an environment that had areas of black rocks as well as …

WebDisruptive selection (diversifying selection) favors the two extreme phenotypes of the trait and minimizes the average phenotype. Thus, disruptive selection creates a bimodal distribution of a trait in the population; consequently, it is the opposite of stabilizing selection in the outcome ( Figure 2.5C ).
