In this study, genetic diversity was evaluated for 40 landraces and improved rice genotypes by inter-simple sequence repeat (ISSR), IRAP (Inter-Retrotransposon Amplified) and REM (Retro transposon-Microsatellite AmplifiedPolymorphism) marker systems. Amplified productions of 20 primers indicated distinct and polymorphic bands among genotypes that produced a total of 309 bands and an average of ...

abstract this study set out to compare the effect of modality of presentation (subtitled vs. auditory) in the comprehension of verbal content of documentary films among iranian efl students. to this end, (30 male 30 female) students were chosen from two schools. after their homogeneity was established, the students attended the listening sessions to watch five documentary films over t...

Molecular markers and mapping are used to analyze an organism’s genes. They allow the selection of target genetic areas based on marker genotype (and not trait phenotype), facilitate study variability diversity, create linkage maps, follow individuals or lines carrying certain may be select parental genotypes, remove drag in back-crossing, choose difficult-to-measure characteristics. Due a lack...

Studies of microsatellites evolution based on marker data almost inherently suffer from an ascertainment bias because there is selection for the most mutable and polymorphic loci during marker development. To circumvent this bias we took advantage of whole-genome shotgun sequence data from three unrelated chicken individuals that, when aligned to the genome reference sequence, give sequence inf...

     Twinning is one of the most important economic traits in goat production, which is influenced by either small or major gene effects. In recent decades, it has been recognized that two members of growth factors originated from oocytes namely GDF9 and BMP15 are essential for follicular development and ovulation. The aim of the current study was to survey the polymorphism of two GDF9 and BMP1...
