Abstract
Karyotype asymmetry is one of the most widely used approaches in cytotaxonomic studies. The symmetry/asymmetry index (S/AI) is used to determine karyotype asymmetry in higher animals and humans. The formula designed by the number of chromosome types is S/AI
= (1 × M) + (2 × SM) + (3 × A) + (4 × T) / 2n. The S/AI value varies from 1.0000 (full symmetric) to 4.0000 (full asymmetric). After a detailed literature review, the chromosomal data of 36 female species and 32 male species of family Cervidae were detected, namely (i) karyotype formulae, (ii) symmetry/asymmetry index values (iii) karyotype types. According to the chromosomal data, two phylogenetic trees were formed. The phylogenetic trees were showed karyotypic relationships among the taxa.
