Seed coat color in soybean is determined by four alleles of the classically defined / (inhibitor) locus that controls the presence or absence as well as the spatial distribution of anthocyanin pigments in the seed coat. By analyzing spontaneous mutations of the / locus, we demonstrated that the / locus is a region of chalcone synthase (CHS) gene duplications. Paradoxically, deletions of CHS gen...

Genetic diversity is getting have been increasingly narrowed by the dense bred cultivar usage for production, on other hand, genetic variation created landraces known as raw material of plant breeding. A collection 21-landrace and three-commercial tomato (Lycopersicon esculentum Mill.) genotypes were screened allele profile, definition similarity with aim identifying variability in level 40 SSR...

Forty-six glioblastomas, 16 anaplastic astrocytomas, and 8 astrocytomas were studied for the loss of the CDKN2 (p16/MTS1) gene on 9p. The CDKN2 locus was homozygously deleted in 19 of 46 glioblastomas (41%) and 1 allele was lost in an additional 13 cases (28%). The deleted regions were limited centromerically in some cases by the MTS2 locus and telomerically by the 1063.7 locus. CDKN2 was homoz...

An importance-sampling method is presented that allows the simulation of the history of a selected allele in a population of variable size. A sample path describing the number of copies of an allele that arose as a single mutant is generated by simulating backwards from the current frequency until the allele is lost. The mathematical expectation of a quantity or statistic is then estimated by t...

The Palm Beach County Sheriffs Office (PBSO) Crime Laboratory and the Alabama Department of Forensic Sciences (ADFS) have validated and implemented analysis of short tandem repeat (STR) sequences on casework using silver staining kit and SYBR Green I detection systems and are presently validating fluorescently tagged STR alleles using the Hitachi FMBIO 100 instrument. Concurrently, the Broward ...

The silver crucian carp (Carassius auratus gibelio), a gynogenetic teleost, is a promising model for the study of evolutionary genetics in vertebrates. We identified ten gynogenetic clones (FZ-I~FZ-X) from triploid silver crucian carp, collected from Fangzheng County in Heilongjiang Province, China, using microsatellite markers. The genetic diversity of these gynogenetic clones was analyzed usi...
