Understanding quantitative genetic variation.
Until recently, it was impracticable to identify the genes that are responsible for variation in continuous traits, or to directly observe the effects of their different alleles. Now, the abundance of genetic markers has made it possible to identify quantitative trait loci (QTL)--the regions of a chromosome or, ideally, individual sequence variants that are responsible for trait variation. What...
متن کاملQuantitative hair form variation in seven populations.
Although hair form has received much attention in the past, it has rarely been studied systematically, and never using direct curling variables. In the present study, seven groups were scored on eight variables, including four newly-devised curling variables. These data were analyzed using univariate and multivariate techniques to give information about the population relations and mechanisms o...
متن کاملNovel microsatellite markers acquired from Rubus coreanus Miq. and cross-amplification in other Rubus species.
The Rubus genus consists of more than 600 species that are distributed globally. Only a few Rubus species, including raspberries and blueberries, have been domesticated. Genetic diversity within and between Rubus species is an important resource for breeding programs. We developed genomic microsatellite markers using an SSR-enriched R. coreanus library to study the diversity of the Rubus specie...
متن کاملمطالعه آناتومی گونههای Rubus زیرجنس Rubus در ایران
جنس تمشک، از تیره Rosaceae، حدود 750 گونه در دنیا دارد که هشت گونه و پنج دورگه آن از ایران گزارش شده است. در پژوهش حاضر، صفات تشریحی ساقه، برگچه، دمبرگ، گوشوارک و دمگل در هفت گونه از جنس تمشک Rubus متعلق به زیرجنس Rubus شامل: R .caesius، R. discolor، R. dolichocarpus، R. hirtus، R. hyrcanus، R .persicus و R. sanctus بررسی شد. نمونههای گیاهی جمعآوری شده در محلول تثبیتکننده قرار گرفته، سپس برش...
