Genome Size And Wing Parameters In Passerine Birds

Amounts of DNA per genome vary more than 7,000-fold among animal species. Some groups such as amphibians exhibit a large range in genome size, whereas others like birds are limited to relatively small genomes. Genome size correlates positively with cell size, which is associated with an inverse relationship between DNA amount and metabolic rate in mammals and birds.
