Although polymorphism of the Y chromosome in bank vole, Myodes glareoulus, is a phenomenon
known for more than 40 years, few studies just pointing to the presence of different types of Y
chromosome, have been done since. Total of 113 males have been caught by live traps at 8 localities
from Serbia. Chromosome preparations were done from bone marrow and karyotypes were analyzed
for the presence of different types of Y chromosome. Two types of Y, metacentric and acrocentric, were
detected. Metacentric Y was prevalent (62.83%). Additionally, differential cytogenetic staining was
done to obtain further information about differences between noticed types of Y. In order to check is
there any dependence of variation in frequencies of metacentric Y and geographic parameters (latitude
and longitude) multiple regression analysis was done. Coeffcient of regression was signifcant (R2 =
0.589; F
(2,5)=6.021, p<0.046) but only latitude showed negative signifcant correlation with frequency
of metacentric Y. Its frequency is increasing from North to South in a range from 0.11 to 1.0.
