the highly conserved morphology and chromosomal structures of house mouse, mus musculus, provides a good model for chromosomal studies. sex-autosome translocations is one of the rarest chromosomal rearrangements among mammals and therefore sex-autosome translocations has been offered as accurate taxonomic markers to identify species with similar morphological traits. in this study, we described...

The S/AI formula is a parameter used to determine the karyotype asymmetry in higher animals and humans. was performed 47 Artiodactyla species. According values between 1.0000 3.0000, dendrograms were drawn demonstrating interspecies interfamilies relationships Artiodactyla. female types are symmetric asymmetric eight families, 18 genera 36 species; five nine 10 full only one family, genus male ...

The subgenus Orithyia in the genus Tulipa is considered one of least studied. It includes most eastern species tulips. Previously, three tulips from this subgenus, T. heteropetala, uniflora, and mongolica were reported for territory Southern Siberia. morphological analysis showed that studied plants, populations previously Siberia under name are large individuals uniflora. There was a high leve...

In this research the metaphase chromosome number and karyotype of Astragalus stenosemioides species growing naturally in Turkey are studied. The study revealed that A. is 2n = 16. basic determined as x 8. formula 8m. total length somatic chromosomes ranges between 1.96 - 3.38 μm. haploid 21.36 addition, asymmetry was evaluated by different methods; Stebbins classification, TF%, AsK%, Syi Rec, A...

The karyotype is a basic concept regarding the genome, fundamentally described by the number and morphological features of all chromosomes. Chromosome class, centromeric index, intra- and interchromosomal asymmetry index, and constriction localization are important in clinical, systematic and evolutionary approaches. In spite of the advances in karyotype characterization made over the last year...

In this report, we describe a mitotic analysis (Giemsa technique) of six species of the genus Vernonia sensu Baker (Asteraceae, Vernonieae, section Lepidaploa) in order to assess the validity of maintaining this genus (sensu Baker) or dividing it into several lesser genera (sensu Robinson). Specimens of the seven species were collected in “cerrado” and “campo rupestre” areas in the states of Sã...

In this study, chromosome length, karyomorphology and asymmetry of six Turkish Muscari species; muglaensis, M. nazimiyensis, pallens, pamiryigidii, inundatum fatmaceranie were evaluated. The somatic number all examined taxa was determined as 2n=18. basic x=9. Chromosomes consist metacentric, submetacentric, subtelocentric chromosomes. This is the first report on morphology for five studied. Stu...

Karyotype study was performed across 7 populations of 4 Rubus species growing in Iran. The results showed that the chromosome numbers of R. sanctus (2n=2x=14) diploid, R. caesius, and R. discolor were (2n=4x=28) tetraploids, R. persicus (2n=8x=56) octoploid. The chromosome numbers of R. discolor, and R. persicus were reported here for the first time. Karyotypic formula also varied between the s...
