Search for: [Description = "Owning to intensive reaserch carried out in different countries, a very complicated variation of common shrew karyotype was revealed, including polymorphism and polytypy. Thirtyseven different Robertsonian matacentrics, 13 different homozygous karyotypes containing only metacentric autosomes, and about 30 different homozygous karyotypes containing metacentric and acrocentric autosomes have actually been found in natural populations. We have calculated the number of theoretically possible karyotypic variants in the common shrew."]
