Species validation:

Species-level identification was carried out by mitochondrial Cytochrome C Oxidase Subunit 1 (COI) DNA barcoding according standard ANSI/ATCC ASN-0003-2015 and revealed Mus musculus species.

Cytogenetics:

murine hypotetraploid karyotype - centric fragment present at 74% - ring present at 48% - 68/69(64-74)<4n> - a submetacentric marker arising by centric fusion present at 52%
