Cytogenetic Characteristics of Microtus guentheri, Microtus arvalis sensu lato and Microtus majori (Mammalia: Rodentia) From Turkey: Constitutive Heterochromatin Distribution
Abstract
Conventionally stained
and C- banded karyotypes of Guenther’s vole (Microtus guentheri), Major's pine vole (Microtus majori) and Common vole (Microtus arvalis) were studied from Turkey. Diploid chromosome numbers of M.
guentheri, M. arvalis and M. majori were found as 2n=54 and
NFa=52, 2n=46 and NFa=68 and 2n=54 and NFa=56, respectively. All chromosomes of M. guentheri were
pericentromeric C- band. In Microtus
arvalis (obscurus cytotype) and Microtus
majori karyotypes,
autosomal chromosomes were heterochromatin C band positive and negative band. In M. arvalis (obscurus cytotype), sex
chromosome was C band negative. In this study, heterozygote chromosome was not found
in the obtained autosomal chromosome set of M.
arvalis. M. majori has enlarged heterochromatin block from
centromere to telomere on the long arm of X chromosome. Y chromosome was
completely heterochromatin.
