Efectos de la heterocromatina supernumeraria sobre la formación de los quiasmas y la actividad nucleolar

Abstract

El significado biológico de los polimorfismos para heterocromatina puede ser esclacido, en parte, mediante el análisis de sus efectos sobre una variedad de caracteres. El más investigado, hasta ahora, es la influencia sobre la formación de los quiasmas, aunque el de este carácter no parece llegar a aclararse. Se revisan aquí los estudios existentes sobre los efectos producidos por los tres principaies tipos de heterocromatina supernumeraria existentes en los saltamontes -cromosomas polisómicos, cromosomas accesorios y segmentos cromosómicos supernumerarios- sobre la frecuencia y distribucih de los quiasmas. Además, examinamos los efectos demostrados en los últimos años por nuestro equipo investigador sobre la actividad de las regiones organizadoras de nucleolo.
