Population structure and seasonal movements of narwhals, Monodon monoceros, determined from mtDNA analysis
We determined the nucleotide sequence of the first 287 base pairs in the mitochondrial control region from 74 narwhals, Monodon monoceros, collected in the North-west Atlantic. We detected four polymorphic sites that defined five haplotypes, two of which were found in single specimens. The same DNA...
