It is known that species belonging to the subgenus Mus have common morphological characters and therefore their morphological differentiation is difficult. In this context, it was aimed to examine some skull characters as well as ZI, H+B/T values used as diagnostic criteria and the ventral edge of the parietal bone. While ZI values were found to vary between 0.24 and 0.52 in Mus domesticus, it was observed to vary between 0.49-1.33 in M. macedonicus. The H+B/T values were found to be between 0.74-1.1 in M. domesticus and between 0.81-1.77 in M. macedonicus. On the dorsal surface of the skull, it was observed that the frontal suture variations tended to be round shaped and the parietal suture variations tended to be v shaped. When the notch status of the upper incisors was examined, it was determined that the ratio of having non-notched and single-notched teeth was close to each other in both species. When the ventral edge of the parietal bone was examined, it was observed that while wavy and straight edges were found in close proportions in M. domesticus, straight edges were predominant in M. macedonicus. When the populations were evaluated according to geographical regions, no significant differences were observed between regions.

Mus altcinsine ait türlerin ortak morfolojik karakterler taşıdıkları ve bu nedenle morfolojik olarak ayrımlarının zor olduğu bilinmektedir. Bu kapsamda teşhis kriteri olarak kullanılan ZI, H+B/T değerleri ve parietal kemiğin ventral durumunun yanında, bazı kafatası karakterlerinin incelenmesi amaçlandı. ZI değerlerinin Mus domesticus’ta 0,24-0,52 arasında değişkenlik gösterdiği tespit edilirken, Mus macedonicus’ta 0,49-1,33 arasında değiştiği gözlendi. H+B/T değerleri ise M. domesticus’ta 0,74-1,1 arasında, M. macedonicus’ta 0,81-1,77 arasında bulundu. Kafatasının dorsal yüzeyinde frontal sutur varyasyonlarının yuvarlak şekilli, parietal sutur varyasyonlarının v şeklinde olma eğiliminde olduğu görüldü. Üst kesici dişlerin çentik durumu incelendiğinde ise her iki türde de çentiksiz ve tek çentikli dişlere sahip olma oranının birbirine yakın olduğu tespit edildi. Parietal kemiğin ventral kenarının durumuna bakıldığında M. domesticus’ta dalgalı ve düz kenarlar birbirine yakın oranlarda bulunurken, M. macedonicus’ta düz kenarların ağırlıklı olduğu görüldü. Popülasyonlar coğrafi bölgelere göre değerlendirildiğinde ise bölgeler arası belirgin farklar gözlenmedi.
