Breeding without Breeding: Is a Complete Pedigree Necessary for Efficient Breeding?
Complete pedigree information is a prerequisite for modern breeding and the ranking of parents and offspring for selection and deployment decisions. DNA fingerprinting and pedigree reconstruction can substitute for artificial matings, by allowing parentage delineation of naturally produced offspring. Here, we report on the efficacy of a breeding concept called "Breeding without Breeding" (BwB) ...
متن کاملPeditree: pedigree database analysis and visualization for breeding and science.
At the Wageningen Laboratory of Plant Breeding, a software package has been developed to query a simple structured database with variety pedigree data. The package, called Peditree, creates a tree-shaped representation of pedigree information and has several visualization and lookup options. Estimates of inbreeding coefficient within a pedigree or coefficients of coancestry among pedigrees can ...
متن کاملExtending pedigree analysis for uncertain parentage and diverse breeding systems.
Breeding programs aimed at conserving genetic diversity in populations of wildlife or rare domestic breeds rely on detailed pedigree analysis for selection of breeders that will minimize the loss of alleles, reduce the accumulation of inbreeding, and maintain gene diversity. Commonly, techniques use a matrix of kinship coefficients to derive measures of genetic variation, inbreeding, and the va...
متن کاملPedigree analysis of four decades of Quarter Horse breeding.
Pedigrees of randomly selected Quarter Horses born in each of the years 1946, 1956, 1966 and 1976 and of winning halter, cutting and race horses born in the same years were evaluated and compared. Average inbreeding and inter se relationship levels and relationships of influential ancestors to the sample were calculated for each sample. The amount of Thoroughbred influence and the average gener...
متن کاملPedigree Analysis and How Breeding Decisions Affect Genes
When evaluating your breeding program, remember that most traits you're seeking cannot be changed, fixed or created in a single generation. The more information you can obtain on how certain traits have been transmitted by your animal's ancestors, the better you can prioritize your breeding goals. Tens of thousands of genes interact to produce a single individual. All individuals inherit pairs ...
