Colonization of the Americas by Drosophila subobscura: lethal-gene allelism and association with chromosomal arrangements.

Genetics - 1 Aug 1995

Mestres F, Serra L, Ayala F J

Abstract excerpt

Drosophila subobscura is a Palearctic species that has recently colonized the Americas. It was first found in 1978 in Puerto Montt, Chile, and in 1982 in Port Townsend, WA. The colonization and rapid expansion of the species in western South and North America provides distinctive opportunities for investigating the process of evolution in action. The inversion polymorphism in the O chromosome from populations of...
