abstract：:Phylogenetic relationships among 27 extant mammalian species (representing 15 placental orders) were studied using sequences of exon 28 of the gene encoding von Willebrand Factor (vWF), a glycoprotein which functions in blood clotting. Analysis of sequences coding for vWF revealed evidence for several subordinal and s...

Studies of duplicate gene loci in tetraploid animals may reveal important general aspects of gene duplication, an important mode of gene evolution in metazoans. The common carp Cyprinus carpio has twice as many chromosomes...
