Using genealogy to improve selection efficiency of pedigree method Emprego da genealogia para melhorar eficiência seletiva no método pedigree

Scientia Agricola, 2008
In the pedigree method of conducting an autogamous population of segregating plants, the genealogy of the progenies is registered. Although labor-intensive, these data are rarely used.

Predicted Residual Error Sum of Squares of Mixed Models: An Application for Genomic Prediction. [PDF]

, 2017
Genomic prediction is a statistical method to predict phenotypes of polygenic traits using high-throughput genomic data. Most diseases and behaviors in humans and animals are polygenic traits. The majority of agronomic traits in crops are also polygenic.

Genetic evaluation of Kankrej bulls by different sire evaluation methods

Indian Journal of Animal Sciences, 2023
The genetic evaluation of Kankrej bulls was done by using three different methods viz., BLUP, Wombat sire, and Wombat animal models. First lactation 305-days yields of 348 daughters born to 9 sires and calved from 2016 to 2020 were used for the analyses.

Evaluating the use of statistical and machine learning methods for estimating breed composition of purebred and crossbred animals in thirteen cattle breeds using genomic information

Frontiers in Genetics, 2023
Introduction: The ability to accurately predict breed composition using genomic information has many potential uses including increasing the accuracy of genetic evaluations, optimising mating plans and as a parameter for genotype quality control.

Predicting cervical cancer DNA methylation from genetic data using multivariate CMMP

Canadian Journal of Statistics, EarlyView.
Abstract Epigenetic modifications link the environment to gene expression and play a crucial role in tumour development. DNA methylation, in particular, is gaining attention in cancer research, including cervical cancer, the focus of this study.
