Cytonuclear genetics of experimental fish hybrid zones inside Biosphere 2.

Proceedings of the National Academy of Sciences of the United States of America - 24 May 1994

Scribner K T, Avise J C

Abstract excerpt

Two species of mosquitofish (family Poeciliidae) known to hybridize in nature were introduced into freshwater habitats inside Biosphere 2, and their population genetics were monitored after 2 years. Within four to six generations, nuclear and cytoplasmic markers characteristic of Gambusia holbrooki had risen greatly in frequency, although some Gambusia affinis alleles and haplotypes were retained primarily in...
