Resumen
Se estudió el efecto de genes normales y deletéreos sobre la fecundidad en seis poblaciones naturales de Drosophila melanogaster; mediante la técnica CyL/Pm, ampliamente usada en Drosophila en análisis semejantes, dependiendo de la población el número de genes normales, deletéreos y letales varió en cada población y a ellos nos referimos en ésta ocasión. Los cromosomas se agruparon en libres y portadores de genes letales y/o delatéreos, estas agrupaciones son la base de las comparaciones hechas mediante la prueba "t" de Student. para ello se obtuvo la fecundidad promedio de cada población y a partir de este se construyeron categorías de fecundidad. Cada cromosoma fue adscrito a una de ellas obteniéndose así las frecuencias relativas para cada categoría. En todos los casos en que se compararon cromosomas portadores de genes letales o libres de ellos, las diferencias favorecieron a los libres de letales.
