The objective of this study was to identify the quantitative trait loci (QTL) affecting carcass traits on chromosome 1 in Japanese quail. The populations comprised of 422 progeny in 9 half-sib families. Phenotypic data on carcass weight, carcass parts, and the internal organs were collected on 422 progeny. Nine half-sib families were genotyped for 8 microsatellite markers covering chromosomes 1...

Eleven populations of five Avena species were analysed for meiotic characters including chiasma frequency and distribution as well as chromosomal association and segregation. Plants of a single population of A. eriantha showed the presence of 2n = 14 (diploid) and 2n = 4x = 28 chromosome number. Populations of A. barbata and A. wiestii possessed n = 14, while populations of A. sterilis ssp. lud...

It has been established that the Y chromosome carries genes required for spermatogenesis and male fertility. For many decades worldwide screening for gene identification has been conducted in research laboratories. However, it has been a difficult process in identifying such genes (i.e. causative mutations) which could explain the phenotypic variation and could be potentially used as markers fo...

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...

Background and Objectives: studying chromosomal changes for anemia patients of children age (3month-12years ) in the city kut diagnosing those abnormalities resulting from having Methods: The chromosomes Patients to were analyzed studied using cytogenetic analysis detect aberrations caused by after collecting blood samples Al-Karama Teaching Hospital as well clinics Kut.Results: Chromosomal all...

We recently described, in Cannabis sativa, the oldest sex chromosome system documented so far plants (12–28 Myr old). Based on estimated age, we predicted that it should be shared by its sister genus Humulus, which is known also to possess XY chromosomes. Here, used transcriptome sequencing of an F1 family H. lupulus identify and study chromosomes this species using probabilistic method SEX-DET...

The success of the Human Genome Project (HGP) has provided a blueprint for the approximately 20,000 gene-encoded proteins potentially active in all of the hundreds of cell types that make up the human body. Yet we still have limited knowledge about a majority of the gene-encoded proteins which are the “building blocks of life” and “cellular machinery”. It is estimated that for nearly half of th...

autism is a complex neuropsychiatric disorder that manifests in early childhood. although the etiology is unknown yet but, new hypothesis focused on identifying the key genes related to autism may elucidate its etiology. the main objective of the present study was to verify the value of karyotyping in autistic children and identifying association between chromosome abnormalities and autism.we e...

meiotic study was performed in 11 brassica napus cultivars considering chiasma frequency anddistribution, chromosome pairing, as well as the occurrence of b-chromosomes and their effects on chiasmafrequency. such cytogenetic pairing, along with agronomic characteristics, may be used in planninghybridization among the b. napus cultivars. all the cultivars studied possessed n=19 chromosome number...
