Genetic contributions and their optimization Tập 132 Số 2 - Trang 89-99 - 2015
J.A. Woolliams, Peer Berg, Binyam S. Dagnachew, T.H.E. Meuwissen
SummaryGenetic contributions were first formalized in 1958 by James and McBride
(Journal of Genetics, 56, 55–62) and have since been shown to provide a unifying
framework for theories of gain and inbreeding. As such they have underpinned the
development of methods that provide the most effective combination of maximizing
gain whilst managing inbreeding and loss of genetic variation. It is shown ho... hiện toàn bộ
Reliable computing in estimation of variance components Tập 125 Số 6 - Trang 363-370 - 2008
I. Misztal
SummaryThe purpose of this study is to present guidelines in selection of
statistical and computing algorithms for variance components estimation when
computing involves software packages. For this purpose two major methods are to
be considered: residual maximal likelihood (REML) and Bayesian via Gibbs
sampling. Expectation‐Maximization (EM) REML is regarded as a very stable
algorithm that is able... hiện toàn bộ
Genome-wide linkage and QTL mapping in porcine F2 families generated from Pietrain, Meishan and Wild Boar crosses Tập 120 Số 6 - Trang 363-393 - 2003

Linkage and QTL mapping for Sus scrofa chromosome 2 Tập 120 Số s1 - Trang 11-19 - 2003
S. S. Lee, Yizhou Chen, C. Moran, S. Čepica, Gerald Reiner, H. Bartenschlager, G. Moser, H. Geldermann
Summary Sus scrofa chromosome 2 (SSC2) linkage maps were generated from three F2
families involving Meishan (M), Pietrain (P) and Wild Boar (W) crosses and the
same 10 marker loci. SSC2 linkage maps were similar between families and
correspond to published maps. Quantitative trait loci (QTLs) for carcass traits,
daily gain and heart weight were identified on SSC2, especially in the intervals
0–20 ... hiện toàn bộ
An efficient algorithm for segregation analysis in large populations Tập 113 Số 1-6 - Trang 457-469 - 1996
Richard J. Kerr, Brian Kinghorn
SummaryA computationally tractable approach to complex segregation analysis for
large data sets is described. This is then used to extend the value of DNA tests
for major locus genotype, by calculating probabilities of belonging to each
genotype class for all animals not DNA tested. Under the conditions simulated,
this approach led to an approximate doubling of the number of animals genotyped
with... hiện toàn bộ
An improved protocol for the production of AFLPTM markers in complex genomes by means of capillary electrophoresis Tập 122 Số 1 - Trang 62-68 - 2005
Riccardo Papa, Michela Troggio, Paolo Ajmone‐Marsan, Francesco Nonnis Marzano
SummaryThe amplified fragment‐length polymorphism (AFLP) technology is a
recently introduced method to investigate genomes of different complexity, from
microbial to higher organisms. It is applied to purposes as diverse as
identification of species, strain and varieties, investigation of genetic
diversity within and between populations, simple and complex trait mapping, and
construction of linkag... hiện toàn bộ
Multi‐breed genetic evaluation in a Gelbvieh population Tập 124 Số 5 - Trang 286-295 - 2007
Andrés Legarra, J. K. Bertrand, T. Strabel, R. L. Sapp, Juan Pablo Sánchez, I. Misztal
SummaryA multi‐breed model was presented for the genetic evaluation of growth
traits in beef cattle. In addition to the fixed effects, random direct and
maternal genetic effects, and random maternal permanent environmental effects
are considered; the model also fits direct and maternal heterosis and direct and
maternal breed‐of‐founder (BOF) × generation group effects using a Bayesian
approach tha... hiện toàn bộ
Analysis of pedigree and conformation data to explain genetic variability of the horse breed Franches‐Montagnes Tập 123 Số 2 - Trang 114-121 - 2006
Pierre-André Poncet, W. Pfister, Jeannette Muntwyler, Marie-Louise Glowatzki-Mullis, Claude Gaillard
SummaryFranches‐Montagnes is the only native horse breed in Switzerland,
therefore special efforts should be made for ensuring its survival. The
objectives of this study were to characterize the structure of this population
as well as genetic variability with pedigree data, conformation traits and
molecular markers. Studies were focused to clarify if this population is
composed of a heavy‐ and a l... hiện toàn bộ
