Use of Cluster Analysis for Identifying Metafounders

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT In the metafounder approach, the relationship matrix of metafounders, Γ$$ \boldsymbol{\Gamma} $$ is used to transfer information on relationships between pedigree founders into the numerator relationship matrix A$$ \mathbf{A} $$, creating matrix AΓ$$ {\mathbf{A}}^{\boldsymbol{\Gamma}} $$.

Analysis of alternative models treating herd × year effects as fixed or random

Czech Journal of Animal Science, 2004
The analysis was conducted of the national database of station tests carried out between May 1996- February 2001, using the Hungarian Large White breed. Days of test, total amount of consumed feed and valuable cuts were taken into the analysis. Using the

Unravelling the Genetic Mechanisms of Litter Traits in a Maternal Line of Pigs

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Reproductive traits related to litter size are the main indicators of reproductive efficiency in pig production and are continuously evaluated for the selection of maternal lines. Several environmental and genetic factors are involved with the development of these traits.

Genetic Parameters and Sex‐Specific Architecture of Observed and Latent Fertility Phenotypes in a Closed Breeding Nucleus of an Arctic Salmonid

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Successful reproduction is a key factor for efficient breeding schemes and sustainable animal farming. Aquaculture breeding programs rely heavily on small fractions of selected breeders to yield large production stocks, given the high fecundity typically observed in these species. In Sweden, Arctic charr (Salvelinus alpinus) is a salmonid with

The transcription factors TaABI4 and TaNAC‐A1 fine‐tune TaCYP94‐A1 transcription to modulate seed dormancy in wheat

Journal of Integrative Plant Biology, EarlyView.
A module involving the transcription factors TaABI4 and TaNAC‐A1, and the cytochrome P450 TaCYP94‐A1 precisely regulates seed dormancy levels through plant hormone crosstalk, providing targets for improving resistance to pre‐harvest sprouting in wheat.

Unknown parent groups and truncated pedigree in single-step genomic evaluations of Murrah buffaloes

Journal of Dairy Science
: Missing pedigrees may produce bias in genomic evaluations. Thus, strategies to deal with this problem have been proposed as using unknown parent groups (UPG) or truncated pedigrees.
