Identification of allelic polymorphism in the ovine leptin gene the current study is the first report on the association of leptin gene polymorphisms with sperm fertility and testicular dimensions in sheep, which suggests leptin gene as a potential gene to be used in breeding programs in order to. Keywords: polymorphism, calpastatin, sheep, pcr-rflp abstrakt kalpastatyna odgrywa ważną rolę polymorphisms in proinflammatory genes and susceptibility to association of cytokine gene the relationship between the leptin gene polymorphism and polymorphism of the tap1 gene in.
Research article allelic polymorphism of k-casein, β-lactoglobulin and leptin genes and their association with milk production traits in iranian the purpose of this study was to investigate the polymorphism of k-casein (k-cn), β-lactoglobulin (b-lg) and leptin (lp) genes in iranian holstein. Allelic frequencies genetic polymorphisms in the leptin gene and their association with fatness in four pig breeds polymorphism of genes encoding for ryanodine receptor, growth hormone, leptin and myc protooncogene protein and meat production in duroc pigs. In sheep, genetic variation in ovulation rate has been widely documented evidence shows substantial difference among breeds and in a number of cases exceptional variations within developmental and hormonal regulation of leptin receptor (ob-r) messenger ribonucleic acid expression in rat testis. Allelic polymorphism of makoei sheep leptin gene identified by polymerase chain reaction and single strand conformation polymorphism polymorphism in the ovine leptin gene (olep) affects leptin-binding affinity and activity 9th world congress on genetics applied to livestock production.
Abstract genetic variation in immunoglobulin a, the most abundant immunoglobulin in mammalian cells, has not been reported in ruminants ogy to the published ovine and bovine igha sequences, suggesting that these sequences represent allelic variants of the igha gene in sheep. There are few articles on exon 3 polymorphism of leptin gene in sheep the polymorphism in the exon 3 of the lep in sheep was also reported by zhou et al (2009) using pcr-sscp technique they reported five unique sscp patterns corresponding to ﬁve allelic sequences using the combination of. Polymorphisms of calpastatin gene in sheep polimorfizm genu kalpastatyny owiec genetic variation between local sheep populations were calculated based on genotypic and allelic frequencies most populations studied were polymorphic, with genotype frequencies of cast-11, cast-12.
While polymorphism in the leptin gene has been thoroughly investigated in bovine and swine, limited information is available on received apr 15 the allelic frequencies were 087 for c and 013 for t in nilagiri sheep the chromatogram showing the snp and the rflp genotyping are shown in fig. Leptin gene polymorphisms and their association with psoriasis have been given very little attention genome-wide association studies have been carried out in order to establish causative genes of psoriasis vulgaris  genetic studies on psoriasis, performed with classical major. Association of polymorphisms in leptin and leptin receptor genes with circulating leptin concentrations, production and efficiency traits in polymorphism of the exon 3 of leptin gene in malpura sheep indian j anim identification of allelic polymorphism in the ovine leptin gene.
In livestock, variation in the leptin (lep) gene has been characterized in cattle and pig, but it has not been reported in sheep in this study, variation in the exon 3 coding sequence of the ovine lep gene was investigated by polymerase chain reaction-single-strand conformational polymorphism. Also, bb genotype of the b-lg gene and aa genotype of the lp gene showed a significant association with protein percentage and milk production (ppolymorphism of k-casein (k-cn), -lactoglobulin (b-lg) and leptin (lp) genes in iranian holstein. A gene is said to be polymorphic if more than one allele occupies that gene's locus within a population in addition to having more than one allele at a specific locus, each allele must also occur in the population at a rate of at least 1% to generally be considered polymorphic.
Polymorphism of the exon 3 of leptin gene in malpura sheep the aim of the present study was to find out an allelic variation in leptin gene of malpura sheep a total of 112 malpura sheep were selected and the genomic dna was isolated by phenol-chloroform extraction method. The allele and genotype frequen- cies of lep and lepr genes were estimated by direct counting, and the differences of the observed and ex- pected the effect of leptin and leptin re- ceptor genes were evaluated in many studies on differ- ent cattle breeds the snp lep/sau3ai have been sig- nificantly. Leptin gene polymorphism is associated with key economic affair considering rich resources for animals, in our country, accomplishing a few assays to identify a gene that controls her traits with molecular genetics, and identifying the candidate genes in sheep breeds using dna test can greatly.
Genetic differences in the leptin gene were first observed in mice ob/ob mice lack functional leptin and are hyperphagic, obese for the allelic frequencies, the frequency of t allele was lower than c allele in both cattle breeds (fig dna polymorphism of leptin gene in bos indicus and bos taurus cattle. Published: mon, 21 may 2018 allelic polymorphisms of leptin gene in najdi and naeimi sheep of saudi arabia genetic variability assessment of the saudi arabian indigenous sheep breeds is important to preserve genetic resources and to develop breeding programs to enhance production. A single-nucleotide polymorphism (snp, pronounced snip plural snips) is a dna sequence variation occurring when a single nucleotide — a, t, c or g — in the genome (or other shared sequence) differs between members of a biological species or paired chromosomes in a human.
Leptin gene milk yield milk composition najdi sheep it is suggested that different effects of najdi genotypes on milk yield during suckling and milking periods may be due to differential expression of lep gene in each period. Sheep farming is of major economic importance, especially for small and marginal farmers because it 12 guan f, liu sr, shi gq, yang lg polymorphism of fecb gene in nine sheep breeds or strains cited by other articles in scincecentral: allelic and genotypic frequencies in polymorphic.
