Three subspecies of Mus musculus have been recognized in Iran so far. The house mouse (genus0T 0T2TMus2T, species0T 0T2TMus musculus2T) are recognized for their highly conserved morphology and chromosomal structure, but some chromosomal characters offer accurate taxonomic markers in this species that has been shown any unambiguous diagnostic morphological traits. Among the chromosomal character...

chromosomal patterns of experimental animals are useful tools for cytogenetics research and animal breeding. chromosome investigations of the hairless guinea pig are rare, therefore, karyotype of hairless guinea pigs (twelve male and female) was studied using metaphase spreads of bone marrows and g banding techniques. the chromosomes diploid number was 2n= 64 and polymorphism of three type chro...

A bionic search architecture has been developed to solve the problem of placing VLSI elementsbased on hybridization algorithms a bee colony and swarm chromosomes,which allows you get out "local holes" increases convergence placement algorithm. The initial iterations are implemented by algorithm provide broad overview ofthe area, final chromosome algorithm,which ensures exact localization extrem...

the present study reports the chromosome number and meiotic behaviour of 14 populationsbelonging to four taxa of anchusa subgenus buglossum gusul. from iran. all populationsshowed the chromosome number 2n= 4x= 32. it is the first meiotic study for a. subg.buglossum. we discuss some habit form and evolutionary aspect in the light of cytogeneticdata. the origin of polyploidy (auto-allopolyploidy)...

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...

The wild-relative gene pools of wheat are a rich source of genetic variation for wheat improvement.Karyotypes of eight genotypes of Triticum monococcum subsp. aegilopoides and eight genotypes of Aegilops cylindrica,which grown wild next to each other in different regions in the west of Iran were studied. Root tips were treated in α-bromonaphthalene solution, fixed in chromic acid-formaldehyde f...

The aim of this paper was to present the second case B chromosomes in Auchenipteridae (Trachelyopterus sp.), and test hypothesis that species Parauchenipterus galeatus might have a common origin, since these two phylogenetic proximity. Both 58 A complement, heterochromatin preferentially located at terminal region most chromosomes, simple Ag-NORs short arm subtelocentric pair, which confirmed b...
