Estimation of genome-wide haplotype effects in half-sib designs.
Genome-wide estimated breeding values can be computed from the simultaneous estimates of the effects of small intervals of DNA throughout the genome on a trait or traits of interest. Small intervals or segments of DNA can be created by the use of thousands of single nucleotide polymorphisms (SNP) available in panels of 10, 25 and 50 thousand SNP. A simulation study was conducted to compare fact...
متن کاملGenetic Variation in Stone Pine Half-Sib Progenies
--Total height, annual height growth, root collar diameter, total number of branches and total number of buds around the leader bud were recorded at age 6. The experimental material was included 136 half-sib families originating from stone pine natural populations from the Carpathian Mountains. Population samples were included in a randomized complete block experiment with four replications and...
متن کاملBias in the prediction of genetic gain due to mass and half-sib selection in random mating populations
The prediction of gains from selection allows the comparison of breeding methods and selection strategies, although these estimates may be biased. The objective of this study was to investigate the extent of such bias in predicting genetic gain. For this, we simulated 10 cycles of a hypothetical breeding program that involved seven traits, three population classes, three experimental conditions...
متن کاملOn the use of linear regression and maximum likelihood for QTL mapping in half-sib designs.
Methods of identification of quantitative trait loci (QTL) using a half-sib design are generally based on least-squares or maximum likelihood approaches. These methods differ in the genetical model considered and in the information used. Despite these differences, the power of the two methods in a daughter design in very similar. Using an analogy with a one-way analysis of variance, we propose ...
متن کاملOptimal haplotype reconstruction in half-sib families
In the goal of genetic improvement of livestock by marker assisted selection, we aim at reconstructing the haplotypes of sires from their offspring. We reformulated this problem into a binary weighted constraint satisfaction problem. Our results showed these problems have a small treewidth and can be solved optimally, improving haplotype reconstruction compared to previous approaches especially...
