The objective of this study was to determine the polymorphism of bovine β-lactoglobulin (β-LG) gene and its association with milk production traits in Iranian Najdi cattle. Blood samples were collected from 80 Najdi cattle from the Najdi cattle breeding station located in Shoshtar, Khuzestan. Polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP) techniqus were used...

Apolipoprotein B (APOB) plays a key role in lipoprotein metabolism and plasma lipid transport. It has been shown that about two-thirds of male mice heterozygous for ApoB were infertile. Moreover, a 3-codon deletion polymorphism (rs11279109) in the signal peptide region of the APOB gene has been shown to be a risk factor for infertility in Slovenian men, but its association with infertility in I...

AIM The aim was to study the polymorphism of exon 2 and exon 3 of growth hormone (GH) gene, to test the polymorphic variants for Hardy-Weinberg equilibrium and to investigate association of these polymorphisms with chest girth and paunch girth in Sirohi and Barbari breeds of goat. MATERIALS AND METHODS A total of 80 kids involving forty each of Sirohi and Barbari breeds of goat were included ...

BACKGROUND An insertion/deletion (I/D) polymorphism in the angiotensin converting enzyme (ACE) gene has been associated with recurrent miscarriage (RM) in several populations. We initiated this study to determine the association, if any, between the I/D polymorphism of ACE gene and RM in Saudi females. METHOD This study was conducted on 61 Saudi females suffering from RM (mean age: 34.1±6.2 y...

Eleven microsatellites were characterized for Semicossyphus pulcher (California sheephead) using an enrichment protocol. The number of alleles varied from three to 14 for a sample of 40 individuals from two populations. Expected heterozygosities ranged from 0.311 to 0.891. All loci but one were in Hardy-Weinberg equilibrium. No evidence for linkage disequilibrium was observed. These polymorphic...

kutum is considered as one of the anadramous species of the caspian sea. due to continuous population decline of the fish since 1975, iranian fisheries organization started to restock this species. nowadays, there is growing concern over the effects of restocking on natural populations. for this purpose, population structure and genetic variation of this species in the iranian coastline of casp...

nuclear markers such as microsatellites have allowed the identification of conservation and management populations of the hawksbill turtles. in present study, eight microsatellite loci were studied. 60 samples of hawksbill turtles. flipper from shidvar and hormuz islands have been surgically removed and preserved in 20% dmso buffer. dna was extracted using dnp kit and amplified by pcr methods. ...

Genetic heterogeneity was investigated using 24 microsatellite markers and genomic DNA of randomly selected birds from the control lines RIR chicken maintained at ICAR-Central Avian Research Institute, Izatnagar. The alleles were determined on urea-PAGE, recorded GelDoc system samples genotyped. complete genotypic data set analyzed POPGENE software. observed heterozygosity (Ho) means 0.6306±0.3...

PURPOSE The expression of natriuretic peptides in the neural bundles of the anterior portion of the optic nerves and their functions in regulating vessel tone and blood flow may suggest a possible role in the pathogenesis of glaucoma. The purpose of this study was to investigate the association between normal-tension glaucoma and the genetic variations of atrial natriuretic peptide (Nppa) and n...
