Alelismo para genes letales en una población natural de Drosophila melanogaster originaria de Mixcoac

Abstract

Una prueba genética para distinguir si dos mutaciones génicas ocurren en el mismo locus funcional, así como establecer sus límites es la llamada prueba de complementación, ampliamente empleada en genética microbiana, el mismo principio se utiliza en agronomía y se conoce como dialelo. En genética de poblaciones y en particular en poblaciones de Drosophila se usa el término prueba de alelismo y es empleada fundamentalmente para determinar distancias genéticas y persistencia de genes en poblaciones naturales y experimentales en las que generalmente se hace para genes letales en condición heterocigota. Así nos propusimos hacer un análisis de éste tipo para genes letales portados en el segundo cromosoma de D. melanogaster extraídos previamente de una población natural originaria de MIxcoac en la Ciudad de México. La prueba consistió en cruzar cada cepa portadora de un gene letal contra todas las demás. Un total de 50 cepas fueron sometidas a dicha manipulación correspondiendo así a 1225 cruzas individuales. Como resultado se obtuvieron 22 cruzas alélicas, distribuidas en 18 sencillas y dos dobles. Finalmente la tasa de alelismo determinada fue de 1.88% que no difiere mucho del promedio reportado por otros investigadores en estudios similares.
