Resumen

Muestras de ratas negras (Rattus rattus) de siete islas del Archipiélago de Galápagos fueron examinadas para estudios de chromosomas. El número diploide de todos los animales es 38 y los cariotipos son idénticos a los de las poblaciones europeas, americanas, y australianas. La conclusión general es que la falta de variabilidad cariotípica de las poblaciones introducidas se explica por la capacidad de ratas de establecerse por medio de cambios fenotípicos.
