Jewel beetles evolve to see new colors by duplicating their genes

WebTo illustrate these forms of selection, let's use an imaginary beetle population, in which beetle color is controlled by many genes and varies in a spectrum from light to dark green. Stabilizing selection. In stabilizing selection, intermediate phenotypes are more fit … Web(Let’s assume an individual’s shape is determined by its alleles for a particular gene). Random groups that depart to establish new colonies are likely to contain different frequencies of squares and circles than the original population. So, the allele frequencies in the colonies (small circles) may be different relative to the original population.
