Natural Selection In A Leopard Frog Population, David J. Merrell
Natural Selection In A Leopard Frog Population, David J. Merrell
Journal of the Minnesota Academy of Science
In a population of immature leopard frogs (Rana pipiens) at Mud Lake, Washington County, Minnesota, a high frequency of unilateral deformity of the hind legs was observed in 1965. Metamorphosis from tadpole to frog took place during July, and samples in late July averaged 14.8% deformed frogs. By late September, the frequency of deformed frogs had decreased to 3.6%, presumably as the result of natural selection.
