PURPOSE To investigate whether the 2 subtypes of advanced age-related macular degeneration (AMD), choroidal neovascularization (CNV), and geographic atrophy (GA) segregate separately in families and to identify which genetic variants are associated with these 2 subtypes. DESIGN Sibling correlation study and genome-wide association study (GWAS). PARTICIPANTS For the sibling correlation study...

What in your view is the distinguishing feature of developmental biology with respect to other natural sciences? It is the source of causality, the genome. Developmental biology differs from other sciences, physics, for example, most profoundly because of the organizing role of the primary informational content of the genome. The genomes of animals are the unique products of a billion years of ...

India has a vast range of medicinal plants at its disposal. Tinospora cordifolia, often known as "Seenthil Kodi" , is dioecious hanging shrub, proven to be valuable botanical for herbal medicine, with an extensive array bioactive components. The goal the current research was determine ideal lines high stem yield and also assess genetic diversity, heritability, advance trait association in crop....

the fact that life styles and personal interests, aggregate within families suggests that shared environment in addition to shared bioligical factors could play a role in determining the phenotypic similarity of idividuals living in the same household. it is a major concern of cardiovascular epidemiologists to know how much of the familial aggregation of blood pressure is attributable to shared...

the aim of this study was to determine the effect of marker density, level of heritability, number of qtls, and size of training set on the genomic accuracy over three generations. thereby, a trait was simulated with heritability of 0.10, 0.25 or 0.40. for each animal, a genome with 20 chromosomes, 1 morgan each, was simulated. different marker densities (2000, 4000 and 6000 markers) and 400 an...

hybrids were produced by crossing female caspian kutum rutilus frisii kutum with male grass carp ctenopharyngodon idella. the genome of eight larvae and parents were studied using microsatellite markers for genetic evaluation and verification. after dna extraction from parent fish and progeny, hybrid heritability of two loci was assessed using two pairs of microsatellite primers. hybridizie...

grapevine is one of the very important fruit crops in iran the fruit of which is used as table grape and/or raisins. in this study, some genetic parameters (phenotypic and genetic correlation, heritability and repeatability), of some important traits in table grape (date of ripening, weight, length and width of berry as well as attachment to cluster strength) were evaluated. results showed high...

fennel (foeniculum vulgare mill.) benefits from a lot of useful medicinal properties. iran is known as one of the main producers of fennel. in spite of high medicinal values, fennel’s cultivation is not economically feasible, mainly due to its low yield. it grows wild in different areas in iran from where diverse ecotypes have evolved. genetic variance and heritability estimates of traits in a ...

The aim of this paper is to assess the heritability of cerebral cortex, based on measurements of grey matter (GM) thickness derived from structural MR images (sMRI). With data acquired from a large twin cohort (328 subjects), an automated method was used to estimate the cortical thickness, and EM-ICP surface registration algorithm was used to establish the correspondence of cortex across the po...
