this study was carried out in order to investigate on chromosomal behavior during meiosis in herbaceum (iranian endemic), arboretum species, f1 hybrids of two species and bc4 genotypes. the endemic varieties used in this study were semnan and shahreza (herbaceum) and vtdl as arboretum cultivar. f1s investigations showed that in the adjacent and alternative quadrivalents frequently but the bc4 o...
Among vertebrates, most of the fishes are unique for the lack of acrosome in their spermatozoa. The sperm enters the egg through micropyle of the egg. This has facilitated heterologous fertilization in many fishes and led to hybridization and polyploidization. Hybridization is performed both in the nature and domesticated fishes. Today, some of the hybrids have high growth rate than their paren...
Homoplasmy is a feature usually found in the mtDNA of higher animal taxa. On the other hand, the presence of two classes of mtDNA in the same cell or organism is rare and may appear in length or site variation. Data from mtDNA RFLP analysis of Brycon opalinus populations (Cuvier, 1819; Characiformes, Characidae, Bryconinae) revealed site heteroplasmy from endonuclease NheI digestion. Southern b...
Objective The Subtelomeric rearrangements are increasingly being investigated in cases of idiopathic intellectual disabilities (ID) and congenital abnormalities (CA) but have also been suspected to be responsible for unexplained recurrent miscarriage (RM). We have noticed a higher risk of subtelomeric translocations in association with CA and ID. Such rearrangements can go unnoticed through con...
The significance of haploid plants as genetic and plant breeding tools has been recognized for a long time. Haploid production techniques including anther culture, isolated microspore culture and intergeneric hybridization between wheat × Hordeum bulbosum and wheat × maize have been used to produce homozygous lines which accelerate breeding programs. In this study, wheat × maize hybridization a...
MOTIVATION It is widely recognized that the hybridization process is prone to errors and that the future of DNA sequencing by hybridization is predicated on the ability to successfully cope with such errors. However, the occurrence of hybridization errors results in the computational difficulty of the reconstruction of DNA sequencing by hybridization. The reconstruction problem of DNA sequencin...

Far-right parties have been increasingly spreading throughout Europe since 1980s; they have attracted the attention of many voters, especially the youth and the workers by campaigning against immigration and multiculturalism. Through an anti-establishment approach, these parties have become mainly mistrustful of the mainstream politics articulating themselves as the true voice of the people and...
In this paper, hybridization is proposed as an alternative approach to sustainable tourism development in Morocco’s southeastern cities. Hybridization refers the integration of multiple elements, such traditional and modern, create a new synthesis that incorporates aspects required from modern building. The evolutionary adopted helps balance between short-term requirements long-term sustainabil...
