Canidae Taksonlarının Karyotip Simetri/Asimetri İndeksi (S/AI) ile Karşılaştırılması

Abstract

The family Canidae is placed in the suborder Caniformia in the order Carnivora. There are both domestic and wild species in Canidae. The family consists of at least 35 wild species in 13 genera. The number of chromosomes in Canidae is divided into 2 groups. (i) The chromosome numbers are 2n = 54, 66, 74, 76, and 78 with mostly acrocentric autosomes. (ii) The chromosome numbers are 2n = 34, 36, 38, and 50 with mostly metacentric and submetacentric autosomes. The formula S/AI measure the symmetry or asymmetry of karyotype in higher animals and humans. In this study, the formula was applied to the Canidae species. After obtaining karyotype formulae with a detailed literature review, S/AI data and karyotype types of 25 female taxa and 17 male taxa were determined. According to the S/AI values, a dendrogram was drawn showing karyological variations among the taxa. The results will contribute to the phylogeny of mammals.
