Restriction enzyme analyses of mitochondrial DNA (mtDNA) of the Black-capped Chickadee (Parus atricapillus), Carolina Chickadee (P. carolinensis), and Tufted Titmouse (P. bicolor) indicate substantial genetic divergence (p = 0.04-0.09). Eleven of 14 enzymes produced fragment patterns that distinguish the two chickadees, revealing a bounty of markers for studies of these sibling species.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
