On the informativeness of dominant and co-dominant genetic markers for Bayesian supervised clustering

چکیده
We study the accuracy of a Bayesian supervised method used to cluster individuals into genetically homogeneous groups on the basis of dominant or codominant molecular markers. We provide a formula relating an error criterion to the number of loci used and the number of clusters. This formula is exact and holds for arbitrary number of clusters and markers. Our work suggests that dominant markers studies can achieve an accuracy similar to that of codominant markers studies if the number of markers used in the former is about 1.7 times larger than in the latter.

MOLECULAR STUDY OF PKD1 & PKD2 GENES BY LINKAGE ANALYSIS AND DETERMINING THE GENOTYPE/PHENOTYPE CORRELATIONS IN SEVERAL IRANIAN FAMILIES WITH AUTOSOMAL DOMINANT POLYCYSTIC KIDNEY DISEASE
ABSTRACT Background: Autosomal dominant polycystic kidney disease (ADPKD) is an inherited disorder with genetic heterogeneity. Up to three loci are involved in this disease, PKDI on chromosome 16p13.3, PKD2 on 4q21, and a third locus of unknown location. Methods: Here we report the first molecular genetic study of ADPKD and the existence oflocus heterogeneity for ADPKD in the Iranian populatio...
متن کاملGenetic analysis of castor (Ricinus communis L.) using ISSR markers
Castor (Ricinus communis L.) is one of the most ancient medicinal oil crops in the world. It has been vastly distributed in different parts of Iran. In the present study, the inter simple sequence repeat (ISSR) markers were used to evaluate the molecular genetic diversity among and within 12 castor accessions collected from 7 regions of Iran. Totally, 16 ISSR primers amplified 166 loci...

Autosomal dominant polycystic kidney disease (ADPKD) is the most common genetic nephropathy, which is characterized by replacement of renal parenchyma with multiple cysts. In Iran, the disease prevalence within the chronic hemodialysis patient population is approximately 8-10%. So far, three genetic loci have been identified to be responsible for ADPKD. Little information is available concernin...
متن کاملGenetic Differentiation of Draa Indigenous Breed and Relationships with Other Goat Populations Assessed by Microsatellite DNA Markers
Moroccan goats are characterized by the presence of different populations identified only based on their phenotypes. The objectives of this study were to assess the genetic differentiation of the Draa goat breed and to analyze its genetic structure and its relationships with other local populations using 12 microsatellite markers. The screening was done in South Eastern and Southern Morocco on ...
متن کاملGenetic Mapping of Blooming Time in ‘Marcona’ × ‘Fragness’ Population with Using Molecular Markers
Flowering time is an important horticultural trait in almond since it is essential to avoid the late frosts that affect production in early flowering cultivars. Evaluation of this complex trait is a long process because of the prolonged juvenile period of trees and the influence of environmental conditions affecting gene expression year by year. In this research flowering time was studied in an...
