Genetic 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 کاملBiased estimation of the recombination fraction using half-sib families and informative offspring.
A maximum-likelihood method to estimate the recombination fraction and its sampling variance using informative and noninformative half-sib offspring is derived. Estimates of the recombination fraction are biased up to 20 cM when noninformative offspring are discarded. In certain scenarios, the sampling variance can be increased or reduced up to fivefold due to the bias in estimating the recombi...
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...
متن کاملGenetic parentage in large half-sib clutches: theoretical estimates and empirical appraisals.
Nearly all of the 906 embryos from a male-tended nest of the sand goby (Pomatoschistus minutus) were genotyped at two hypervariable microsatellite loci to document conclusively the number of mothers and their relative genetic contributions to the nest. The true number of mothers determined by this nearly exhaustive genetic appraisal was compared to computer simulation treatments based on allele...
متن کاملMaximum likelihood estimation of linkage disequilibrium in half-sib families.
Maximum likelihood methods for the estimation of linkage disequilibrium between biallelic DNA-markers in half-sib families (half-sib method) are developed for single and multifamily situations. Monte Carlo computer simulations were carried out for a variety of scenarios regarding sire genotypes, linkage disequilibrium, recombination fraction, family size, and number of families. A double hetero...
