Hybrids were produced by crossing female Caspian kutum Rutilus frisii kutum with male grass carp Ctenopharyngodon idella. The genome of eight larvae and parents were studied using microsatellite markers for genetic evaluation and verification. After DNA extraction from parent fish and progeny, hybrid heritability of two loci was assessed using two pairs of microsatellite primers. Hybridizie...

  Gene families are considered as groups of homologous genes which they share very similar sequences and they may have identical functions. Members of gene families may be found in tandem repeats or interspersed through the genome. These sequences are copies of the ancestral genes which have underwent changes. The multiple copies of each gene in a family were constructed based on gene duplicati...

Genetic maps with high genome coverage are becoming increasingly useful in both basic and applied genetic researches. In the last decades, the advent of DNA markers has brought about a magnificent revolution in the production of genetic map, especially in wheat. In the present study, AFLP markers were used to saturate linkage map of 107 doubled haploid individuals produced through Fukuho _Komug...

this study aimed to identify genes that show signatures of selection for mutations in iranian native cattle breeds. the data consisted of genotypes for ~777962 snp markers of 90 animals from eight iranian native cattle breeds distributing over the country. therefore, the aim was to identifying divergently selected regions of the genome. study of population differentiation across the genome usin...

Inbreeding depression is a harmful phenomenon in livestock which is outcome of inbreeding. Inbreeding is consequence mating between two individuals who are more related to each other than average relatedness in population, which results in reducing in fitness of progenies and genetic variability in populations. Development of high-density genome-wide single nucleotide polymorphism (SNP) array f...

The autism spectrum disorders (ASD) are amongst the most heritable complex disorders. Although there have been many efforts to locate the genes associated with ASD risk, many has been remained to be disclosed about the genetics of ASD. Scrutiny's have only disclosed a small number of de novo and inherited variants significantly associated with susceptibility to ASD. These only comprise a small ...

In order to perform breeding programs and improve production of native chickens, preserving genetic diversity in different areas of Iran is important due to the reduced available population. Genome sequencing is considered the most functional approach to determine the phylogeny relation between close populations. The aim of the present study was the evaluation of the phylogeny and genetic nucle...

differentiation of stem cells from a pluripotent to a committed state involves global changes in genome expression patterns, the best known as “epigenetic modifications”. epigenetic mechanisms, including histone modifications, dna methylation and non-coding rna-mediated regulatory events are considered as the essential factors to control the heritable cellular memory of gene expression during d...

decrease in genome content may play a role in environmental adaptation. many studies were reported significant correlation between genome size, weather condition and germination percentage. relative genome content and its correlation with seedling establishment of 14 populations of tall fescue collected from various regions in iran and two commercial tall fescue cultivars were studied under dro...
