Explicación: Para algunas condiciones, tener una copia mutada de un gen en cada célula es ventajoso, mientras que tener dos copias mutadas causa la enfermedad. El ejemplo mejor estudiado de este fenómeno es la enfermedad de células falciformes: tener dos copias mutadas del gen HBB en cada célula da como resultado la enfermedad, pero tener solo una copia proporciona cierta resistencia a la malaria. Esta resistencia a la enfermedad ayuda a explicar por qué las mutaciones que causan la enfermedad de células falciformes todavía se encuentran en muchas poblaciones, especialmente en áreas donde prevalece la malaria.
