Immunological Resolution of a Diploid-Tetraploid Species Complex of Tree Frogs (original) (raw)

Science, 1977

Abstract

Micro-complement fixation studies of eastern and western populations of the North American tree frog Hyla chrysoscelis reveal they have been genetically isolated for about 4 million years. Immunological comparisons of populations of the cryptic tetraploid Hyla versicolor indicate a recent origin, from hybridization between eastern and western H. chrysoscelis.
