Popis
This study compared the genetic variability of Louisiana barn swallows at a dioxincontaminated wetland to two reference populations. Allozyme frequencies, determined by starch gelcellulose acetate electrophoresis, were used to compare genetic variation. This was the first study of this type using avian species, the results failed to show genetic alteration in the potentially contaminated population compared to the reference populations. The barn swallows from the contaminated site were genetically more similar to one of the reference populations than were the reference populations to each other.
