Resumen

Resumen
La comprensión de la base genética de la variación fenotípica y de los mecanismos que intervienen en la evolución de la novedad adaptativa, especialmente en las radiaciones adaptativas, es un objetivo importante de la biología evolutiva. Aquí, utilizamos datos de secuencia de todo el genoma para investigar el origen de la barra de ala trasera amarilla en la radiación Heliconius cydno. Encontramos variación modular asociada con el fenotipo de ala posterior en dos regiones estrechas no codificantes aguas arriba y aguas abajo del gen de la corteza, el cual fue identificado recientemente como un controlador de patrones de pigmentación en múltiples especies de Heliconius. La variación genética en cada uno de estos módulos sugiere un control independiente del patrón dorsal y ventral del ala posterior, con el módulo aguas arriba asociado al fenotipo ventral y el módulo aguas abajo al dorsal. Además, detectamos introgresión entre H. cydno y sus especies estrechamente relacionadas Heliconius melpomene en estos módulos, lo que probablemente permitirá a ambas especies participar en nuevos anillos de mimetismo. En resumen, nuestros hallazgos apoyan el papel de la modularidad regulatoria junto con la introgresión adaptativa como un mecanismo elegante mediante el cual las combinaciones fenotípicas novedosas pueden evolucionar y alimentar una radiación adaptativa.
