Twelve new polymorphic microsatellite loci were developed for the hard-shelled mussel, Mytilus coruscus. In 32 individuals from a wild population of coastal Zhoushan, Zhejiang Province, China, the number of alleles at these loci varied from 3 to 15, with a mean of 5.667. The mean observed and expected heterozygosities were 0.6927 and 0.6591, respectively. Among these polymorphic microsatellite ...

pedigree information and phenotypic records are the key features in animal genetics and breeding. otherwise best methods for genetic evaluation and estimation of parameters will be tending to no correct results. this study was aimed to investigate and verify pedigree relations among 76 individuals who were genotyped for 3 fluorescent labeled microsatellite markers picked up from fao-isag joint ...

Microsatellites are popular genetic markers in molecular ecology, genetic mapping and forensics. Unfortunately, despite recent advances, the isolation of de novo polymorphic microsatellite loci often requires expensive and intensive groundwork. Primers developed for a focal species are commonly tested in a related, non-focal species of interest for the amplification of orthologous polymorphic l...

Twelve polymorphic microsatellite loci were developed in the multiband (pebbled) butterflyfish Chaetodon multicinctus. The loci were scored in 45 individuals from Hawaii. There were five to 21 alleles per locus with observed heterozygosity ranging from 0.419 to 0.883. Four of the primer sets also reliably amplified polymorphic loci in Chaetodon quadrimaculatus. We expect these markers to be use...

The objective of this study was to screen single nucleotide polymorphisms (SNPs) of the chicken lipoprotein lipase gene (LPL), using 545 F1 hybrids developed from 4×4 diallel crossing of four chicken breeds, and to analyze the associations between polymorphisms of the LPL and chicken fat deposition traits. PCR-SSCP was used to detect SNPs in LPL. Fifteen sets of primers were designed to amplify...

The mapping of functional genes plays an important role in studies of genome structure, function, and evolution, as well as allowing gene cloning and marker-assisted selection to improve agriculturally important traits. Simple sequence repeats (SSRs) developed from expressed sequence tags (ESTs), EST-SSR (eSSR), can be employed as putative functional marker loci to easily tag corresponding func...

DNA polymerase alpha is the most highly scrambled gene known in stichotrichous ciliates. In its hereditary micronuclear form, it is broken into >40 pieces on two loci at least 3 kb apart. Scrambled genes must be reassembled through developmental DNA rearrangements to yield functioning macronuclear genes, but the mechanism and accuracy of this process are unknown. We describe the first analysis ...

Immunopositivity for the p53 tumor suppressor gene product was evaluated in 133 breast cancers and compared to loss of heterozygosity (LOH) at various chromosomal loci. The validity of p53 immunopositivity as an indicator for p53 mutations was verified using two molecular assays of p53 mutations: single stranded conformational polymorphism (32 cases) and/or direct sequencing (14 cases). Immunop...

berari goats are medium sized animals reared mainly for meat purpose. they are predominantly brown and blackish brown in colour with glossy hair and found in vidarbha region of maharashtra state. berari is not a recognized breed but a well established local population of goat which is yet to be fully explored for its phenotypic and genetic aspects. within population genetic variation was examin...

Kidney tumors from stilbene estrogen (diethylstilbestrol)-treated Syrian hamsters were screened for somatic genetic alterations by Random Amplified Polymorphic DNA-polymerase chain-reaction (RAPD-PCR) fingerprinting. Fingerprints from tumor tissue were generated by single arbitrary primers and compared with fingerprints for normal tissue from the same animal, as well as normal and tumor tissues...
