Aspectos del polimorfismo genético en Drosophila pseudoobscura, D. willistoni y D. nebulosa Aspects of genetic polymorphism in Drosophila pseudoobscura, D. willistoni and D. nebulosa

open access: yesActa Agronómica, 2008
En México el polimorfismo cromosómico en poblaciones naturales de Drosophila se estudió en D. pseudoobscura, D. willistoni y D. nebulosa. En la primera, más ampliamente analizada, se reconocen 27 inversiones correspondientes al 67.5% de la variabilidad ...
