Two new karyotypes and bandings in Microtus mandarinus faeceus (Rodentia)

Here we report our study on two new karyotypes and C‐bandings of M. m. faeceus. Our study shows that there are polymorphisms in the X chromosome of M. m. faeceus (Rodentia), which exibitsubtelocentric XST, metacentric XM and submetacentric XSM patterns, respectively. One new karyotype formula is: 2n...

Description
Summary:Here we report our study on two new karyotypes and C‐bandings of M. m. faeceus. Our study shows that there are polymorphisms in the X chromosome of M. m. faeceus (Rodentia), which exibitsubtelocentric XST, metacentric XM and submetacentric XSM patterns, respectively. One new karyotype formula is: 2n = 49 = 4sm + 42t + 1m + XX (sm,sm), and the sex chromosomes are: XM XSM; The other new karyotype formula is: 2n = 50 = 4sm + 43t + 1m + XX (sm,sm), and the sex chromosomes are: XSMXSM. One C‐banding karyotype formula is: 2n = 49 = 4sm + 44t + X(st)0, and the sex chromosome is: XSTO and the other C‐banding karyotype formula is: 2n = 50 = 4sm + 44t + XY(m,t), and the sex chromosomes are: XM Y.
