In this study, we considered five categories of molecular markers in clonal F1 and double cross populations, based on the number of distinguishable alleles and the number of distinguishable genotypes at the marker locus. Using the completed linkage maps, incomplete and missing markers were imputed as fully informative markers in order to simplify the linkage mapping approaches of quantitative t...

Retrotransposons are abundant in the genomes of plants. In the present study, inter-retrotransposon amplified polymorphism (IRAP) and retrotransposon-microsatellite amplified polymorphism (REMAP) markers were developed for the cassava genome (Manihot esculenta Crantz). Four cassava cultivars (Fécula Branca, IPR-União, Olho Junto, and Tamboara, two samples per cultivar) were used to obtain IRAP ...

Genetic association studies determine how genes influence traits. However, non-detected population substructure may bias the analysis, resulting in spurious results. One method to detect substructure is to genotype ancestry informative markers (AIMs) besides the candidate variants, quantifying how much ancestral populations contribute to the samples' genetic background. The present study aimed ...

We analyzed the European genetic contribution to 10 populations of African descent in the United States (Maywood, Illinois; Detroit; New York; Philadelphia; Pittsburgh; Baltimore; Charleston, South Carolina; New Orleans; and Houston) and in Jamaica, using nine autosomal DNA markers. These markers either are population-specific or show frequency differences >45% between the parental populations ...

The nature of brown adipose tissue in humans is presently debated: whether it is classical brown or of brite/beige nature. The dissimilar developmental origins and proposed distinct functions of the brown and brite/beige tissues make it essential to ascertain the identity of human depots with the perspective of recruiting and activating them for the treatment of obesity and type 2 diabetes. For...

Seventy three sisters of boys with Duchenne muscular dystrophy and their families were studied using up to seven deoxyribonucleic acid (DNA) probes linked to the gene on the short arm of the X chromosome. Fifty three (73%) were informative for flanking markers, a further 18 (24%) being informative for a single marker only. Predictions based on pedigree structure and creatine kinase information ...

Background & Aims: SLC26A4 gene mutations are the second identifiable genetic cause of autosomal recessive nonsyndromic hearing loss (ARNSHL) after GJB2 mutations and are currently investigated in molecular diagnosis.In databases, several potential STR markers related to this region have been introduced. In this investigation, the characteristics and informativeness of D7S2425 CA repeat STR mar...
