Bu çalışmada
Türkiye’nin üç faklı lokalitesinden elde edilen üç farklı türe ait ( Crocidura suaveolens, Crocidura leucodon, Sorex raddei) 5 küçük memeli hayvanın standart karyotipi ve C band
yöntemi kullanılarak kromozomlardaki heterokromatin dağılımı araştırılmıştır. Crocidura suaveolens karyotipi 2n=40,
temel kromozom kol sayısı (NFa)= 46, X=submetasentrik (SM), Y=akrosentrik (A); Sorex raddei karyotipi 2n=36, NFa=66,
X=A, Y=A; Crocidura leucodon
karyotipi 2n=28, NFa= 46, X=SM, Y=A şeklindedir. C. suaveolens, C.leucodon,
S. raddei karyotiplerinde C-bant
heterokromatin dağılımı Türkiye populasyonlarında ilk defa bu çalışma ile
tanımlanmıştır.

Cytogenetic Characteristics of Crocidura suaveolens, Crocidura leucodon, Sorex raddei (Mammalia: Eulipotyphla) from Turkey: Constitutive Heterochromatin Distribution

Öz

In this study, heterochromatin
distribution in the chromosomes of five small mammals of three different species
(Crocidura suaveolens, C. leucodon, Sorex raddei) from four different localities of Turkey were inestigated by
using standard karyotype and C-banding method. Crocidura suaveolens karyotype included 2n=40 chromosomes,
fundamental number of autosomal arms (NFa)= 46, X=submetacentric (SM),
Y=acrocentric (A); Sorex raddei
karyotype was 2n=36, NFa=66, X=A, Y=A;
Crocidura leucodon karyotype was 2n=28, NFa= 46, X=SM, Y=A. C-banding
heterochromatin distribution in C.
suaveolens, C.leucodon, S. raddei karyotypes was reported in
this study for the first time in Turkey populations.
