The Karyotype of Blainville ’s Beaked Whale, < b > < i > Mesoplodon densirostris < /i > < /b >

The karyotype of the Odontocete whale,Mesoplodon densirostris, has not been previously reported. The chromosome number is determined to be 2n = 42, and the karyotype is presented using G-, C-, and nucleolar organizer region (NOR) banding. The findings include NOR regions on 2 chromosomes, regions of heterochromatic variation, a large block of heterochromatin on the X chromosome, and a relatively large Y chromosome. The karyotype is compared to published karyograms of 2 other species ofMesoplodon.Cytogenet Genome Res
