The Barbarine sheep is generally managed within small interconnected herds. The goal of the present work is to investigate the effect of the mating management on genetic variability in a registered flock which starts showing a productivity falling, especially in lamb’s survival and this despite a practice of outbreeding. Pedigree data of 11 136 animals born between 1977 and 2007 were used to co...

This article deals with the estimation of inbreeding and substructure levels in a set of 10 (later regrouped as eight) African-derived quilombo communities from the Ribeira River Valley in the southern portion of the state of São Paulo, Brazil. Inbreeding levels were assessed through F-values estimated from the direct analysis of genealogical data and from the statistical analysis of a large se...

Lately, genealogy has become a hobby not only in the United States, UK or France but also in many other countries where it is now widespread. The main sources of information for genealogists are different kinds of genealogical documents (census, church vital records, wills, ...). In fact, and specifically in Spain, several projects to digitalize heritage and genealogical documentation have deve...

AIM To investigate using a Western Australian (WA) genealogical database for the identification of single gene and chromosome disorders among families. METHOD Hospital admissions for single gene and chromosome disorders recorded during 2000-2006 were identified from the WA Hospital Morbidity Data System. The proportion of these conditions occurring in family groups was then identified using g...

Abstract In a population with haploid reproduction any individual has a single parent in the previous generation. If all genealogical distances among pairs of individuals (generations from the closest common ancestor) are known it is possible to exactly reconstruct their genealogical tree. Unfortunately, in most cases, genealogical distances are unknown and only genetic distances are available....

The pyridoacridine natural products represent a large and growing class and serve here to illustrate the wealth of information that can be extracted by comparing natural products on the basis of structure and occurrence.

Genome-wide SNP data provide a powerful tool to estimate pairwise relatedness among individuals and individual inbreeding coefficient. The aim of this study was to compare methods for estimating the two parameters in a Finnsheep population based on genome-wide SNPs and genealogies, separately. This study included ninety-nine Finnsheep in Finland that differed in coat colours (white, black, brow...
