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.
Novelty Statement | This is the first report on karyotype asymmetry of Cervidae. Karyotypic relationships are useful to infer processes of evolution and speciation. Karyotype asymmetry is an important parameter that helps to establish phylogenetic relationships among various species.
