1. Renal volume of five-year-old preterm children are not different than full-term controls
Abstract Objective: In previous studies, smaller renal volumes were reported in prematurely born infants, however, these renal volumes were not corrected for body surface area, the main determinant of renal size. Given the rapid growth of the renal cortex after premature birth, the authors hypothesized that corrected volumes would not differ from healthy co

2. Mapeamento de QTL para características de crescimento de suínos por meio de modelos de regressão aleatória
O objetivo deste trabalho foi avaliar eficiência de modelos de regressão aleatória (MRA) para detectar locus de características quantitativas (QTL) para características de crescimento, em suínos. Utilizou-se uma população divergente F2 Piau x Comercial. A eficiência da metodologia proposta na detecção de QTL foi comparada à da metodologia tradici

3. Regressão aleatória na detecção de QTL para características de crescimento de suínos / Random regression to detect QTL for growth traits in swine
Muitos estudos são voltados para a busca de QTL (locos de características quantitativas) que afetam características de crescimento em suínos, sendo que a quase totalidade tem encontrado QTL com efeitos significativos. No entanto, a maioria destes estudos utiliza informações referentes a peso corporal em idades específicas ou ganho de peso médio. Dess

4. Genetic variability in common wheat germplasm based on coefficients of parentage
The characterization of genetic variability and an estimate of the genetic relationship among varieties are essential to any breeding program, because artificial crosses among less similar parents allow a larger segregation and the combination of different favorable alleles. Genetic variability can be evaluated in different ways, including the Coefficient of

6. Fine-mapping of quantitative trait loci by identity by descent in outbred populations: Application to milk production in dairy cattle
We previously mapped a quantitative trait locus (QTL) affecting milk production to bovine chromosome 14. To refine the map position of this QTL, we have increased the density of the genetic map of BTA14q11–16 by addition of nine microsatellites and three single nucleotide polymorphisms. Fine-mapping of the QTL was accomplished by a two-tiered approach. In

7. Proportion of Genes Survived in Offspring Conditional on Inheritance of Flanking Markers
In mammalian genetics and perhaps in human genetics as well, it is an interesting question as to how many offspring are needed in order to have a desired chance of preserving part or the entire genome of an individual. A more practical and perhaps more important question is: given k children and DNA marker data on a particular region of interest, what propor

8. Minimum-Recombinant Haplotyping in Pedigrees
This article presents a six-rule algorithm for the reconstruction of multiple minimum-recombinant haplotype configurations in pedigrees. The algorithm has three major features: First, it allows exhaustive search of all possible haplotype configurations under the criterion that there are minimum recombinants between markers. Second, its computational requirem

9. Trials of the beta model for complex inheritance.
Theoretical advantages of nonparametric logarithm of odds to map polygenic diseases are supported by tests of the beta model that depends on a single logistic parameter and is the only model under which paternal and maternal transmissions to sibs of specified phenotypes are independent. Although it does not precisely describe recurrence risks in monozygous t

10. Haplotypic Background of a Private Allele at High Frequency in the Americas
Recently, the observation of a high-frequency private allele, the 9-repeat allele at microsatellite D9S1120, in all sampled Native American and Western Beringian populations has been interpreted as evidence that all modern Native Americans descend primarily from a single founding population. However, this inference assumed that all copies of the 9-repeat all

11. Search for consanguinity within and among families of patients with trichothiodystrophy associated with xeroderma pigmentosum.
The association of two rare hereditary disorders, trichothiodystrophy (TTD) and xeroderma pigmentosum (XP), was found in four patients from three families, apparently unrelated but living in the same geographical area. In order to test the hypothesis of a common ancestor, consanguinity within and among the families was checked using three different approache

12. Intraspecific genetic diversity of Oenococcus oeni as derived from DNA fingerprinting and sequence analyses.
The intraspecific genetic diversity of Oenococcus oeni, the key organism in the malolactic fermentation of wine, has been evaluated by random amplified polymorphic DNA (RAPD), ribotyping, small-plasmid content, and sequencing of RAPD markers with widespread distribution among the strains. Collection strains representing the diversity of this species have bee
