one of the traits of the greatest financial impact on sheep production is the number of lambs weaned per ewe with fecb considered as the most well known major gene concerned with this trait. in order to conduct a marker assisted introgression (mai) program the presence of fecb responsible mutation in afshari sheep breeding flock was surveyed. direct test to detect fecbb allele was conducted on ...

the main objective of this study was to assess genetic comparison of two migratory forms of caspian trout salmo trutta caspius namely fall-run and spring-run. owing to the lack of information on its genetic differences, 5 microsatellite loci were used for 58 sample analyses. genomic dna was extracted from caudal fin using roche dna extraction kit and each pcr reaction was performed in a 25 ?l r...

Heterozygosity is a metric of genetic variability frequently used to inform the management threatened taxa. Estimating observed and expected heterozygosities from genome-wide sequence data has become increasingly common, these estimates are often derived directly genotypes at single nucleotide polymorphism (SNP) markers. While many SNP markers can provide precise processes, results ‘downstream’...

Heterozygosity has been associated with components of fitness in numerous studies across a wide range of taxa. Because heterozygosity is associated with individual performance it is also expected to be associated with population dynamics. However, investigations into the association between heterozygosity and population dynamics have been rare because of difficulties in linking evolutionary and...

Objective(s): Iran is considered as one of the high-prevalence areas for β-thalassemia with a rate of about 10% carrier frequency. Molecular diagnosis of the disease is performed both by direct sequencing and indirectly by the use of polymorphic markers present in the beta globin gene cluster. However, to date there is no reliable information on the application of the markers in the Iranian pop...

the present study was to construct a parentage verification system for iranian caspian horse. a total number of 45 caspian horse samples including 14 foals for parentage verification, 17 stallion and 14 mare for individual identification were genotyped. genomic dna was extracted from whole blood and the genotype were analysed by pcr procedure and using 7 microsatellite markers (aht04, hms03, hm...

The present study was to construct a parentage verification system for Iranian Caspian horse. A total number of 45 Caspian horse samples including 14 foals for parentage verification, 17 stallion and 14 mare for individual identification were genotyped. Genomic DNA was extracted from whole blood and the genotype were analysed by PCR procedure and using 7 microsatellite markers (AHT04, HMS03, HM...

To clarify the genetic relationships among the Lidia breed lineages and two main Portuguese Lidia bovine populations, Casta Portuguesa and Brava dos Açores, 24 autosomal microsatellites were analyzed in 120 samples. Brava dos Açores showed the highest observed and expected heterozygosity (0.73 and 0.70, respectively) while Casta Portuguesa showed the lowest observed and expected heterozygosity ...

The pituitary-specific transcription factor (PIT-1) gene is a candidate gene for growth, carcass and also for milk yield traits. In dairy farm animals, the main goal of the selection is the improvement of milk yield and composition. The genes of milk proteins and hormones are excellent candidate genes for linkage analysis with quantitative trait loci (QTL) because of their biological significan...
