You have several hives of honey bees, that you keep in your backyard. Some bees uncap and remove dead larvae from cells, while others leave dead large in the cells; this difference is genetically determined. After a particularly hot summer in which many bees die from disease, you notice that the only gives remaining are the ones in which bees uncap and remove dead larvae. You have witnessed
