Population genetics has come of age. Three important components have come together: efficient techniques to examine informative segments of DNA, statistics to analyse DNA data and the availability of easy-to-use computer packages. Single-locus genetic markers and those that produce gene genealogies yield information that is truly comparable among studies. These markers answer biological questio...

This study describes the application of a simple and effective method to isolate SSR markers from oil palm genomic sequences. A total of 12 informative SSR markers are described. The SSR markers were found suitable for genome analysis and DNA fingerprinting of oil palm tissue culture clones. Eleven of the 12 SSR markers exhibited expected Mendelian segregation ratios when tested on a mapping po...

In order to identify representative genetic alterations in esophageal squamous cell carcinomas (ESCC) and useful markers for future early detection, 34 ESCC samples with neighboring normal epithelia and 30 esophageal biopsy samples from Linzhou, P.R. China, were studied. Of the 38 microsatellite markers selected, half were linked with tumor suppressors. More than 40% of the tumor samples showed...

Restriction fragment length polymorphisms (RFLPs) within or close to the factor VIII locus are very useful for genetic linkage analysis. Such RFLPs allow a mutant allele to be tracked in a family, segregating haemophilia A even when, as is usually the case, the precise mutation causing failure to synthesise factor VIII is unknown. To date two markers tightly linked to the factor VIII locus have...

We evaluated the presence or absence of informative morphogenetic variants in cases with mental retardation compared with mentally healthy subjects. Cases diagnosed with mental retardation were matched by age and sex with control subjects and examined for the presence of informative morphogenetic variants. The aim of the study was to investigate their prevalence and mean number in these subject...

Leaf development has been monitored chiefly by following anatomical markers. Analysis of transcriptome dynamics during leaf maturation revealed multiple expression patterns that rise or fall with age or that display age-specific peaks. These were used to formulate a digital differentiation index (DDI) based on a set of selected markers with informative expression during leaf ontogeny. The leaf-...

Estimating the line origin of chromosomal sections from marker genotypes is a vital step in quantitative trait loci analyses of outbred line crosses. The original, and most commonly used, algorithm can only handle moderate numbers of partially informative markers. The advent of high-density genotyping with SNP chips motivates a new method because the generic sets of markers on SNP chips typical...
