The existence of genetic diversity in has globally remained a mystery till date. The study investigated PCR based DNA amplification profile of saffron using ISSR and RAPD based primers. A total of 38 amplicons were generated by ISSR primers in the range from 7 to 12 with an average of 9.50 bands per primer. 20 bands were found to be polymorphic and 18 were monomorphic with an average percentage of polymorphism as 52.48%. RAPD based amplification revealed a total 161 amplicons, 107 as polymorphic and 54 as monomorphic with an average percentage of polymorphism as 66.44%. Cumulative results of RAPD and ISSR demonstrated that Nei-Li's similarity index ranged between 0.70 and 0.97. The results of AMOVA has revealed 9% of variance among populations and 91% of variance within populations, Φ PT was found as 0.089, which indicates existence of genetic differences though limited. In conclusion, the results indicate that saffron accessions are minimally genetically differentiated, which could be capitalized in future breeding programmes to ameliorate this precious crop.

Introduction: LDL-cholesterol greater than 190 mg/dL indicates severe hypercholesterolemia (HS) of monogenic and/or polygenic origin. Genetic risk scores (GRS) evaluate potential polygenic causes.
Objective: we applied a GRS of 6-SNP (GRS-6) in HS individuals.

Faecal samples were collected from 216 Tibetan pigs and 78 Tibetan Yorkshire (Large White) and 53 tissue samples from Yorkshire from the Linzhi City slaughterhouse. Total RNA was extracted from faeces and fragments of HEV open reading frame 2 (ORF2) detected by reverse transcription and nested polymerase chain reaction (RT-nPCR) and cloned.

Dwarfism is a major trait for developing lodging-resistant rice cultivars. Gamma irradiation-induced mutagenesis has proven to be an effective method for generating dwarf rice mutants. In this research, we isolated a dwarf mutant from Anna R (4) in the M generation and subsequently stabilized the trait through successive selfing of progeny across the M-M generations.

Genetic differentiation in traits is assumed to frequently occur in response to divergent natural selection. For example, developmental traits might respond to differences in climate. However, little is known about when and at which spatial scales environmental differences lead to genetic differentiation, and to what extent there is genetic differentiation also in trait plasticity.
