Reducing computational demands of restricted maximum likelihood estimation with genomic relationship matrices

Genetics Selection Evolution, 2023
Restricted maximum likelihood estimation of genetic parameters accounting for genomic relationships has been reported to impose computational burdens which typically are many times higher than those of corresponding analyses considering pedigree based ...

Genomic estimates of Identity-By-Descent relationships in large scale data sets [PDF]

Genetics Selection Evolution
Background Genomic relationship and inbreeding estimates are either based on genetic drift (e.g. the Genomic Relationship Matrix; GRM), homozygosity (e.g. Runs of Homozygosity; ROH), or Identity-By-Descent (IBD).

Assessment of relationships between pigs based on pedigree and genomic information

Animal, 2020
Relationships play a very important role in studies on quantitative genetics. In traditional breeding, pedigree records are used to establish relationships between animals; while this kind of relationship actually represents one kind of relatedness, it ...

Efficient Calculation of the Genomic Relationship Matrix [PDF]

, 2020
Since the calculation of a genomic relationship matrix needs a large number of arithmetic operations, fast implementations are of interest. Our fastest algorithm is more accurate and 25× faster than a AVX double precision floating-point implementation.

Invited review: efficient computation strategies in genomic selection

Animal, 2017
The purpose of this study is review and evaluation of computing methods used in genomic selection for animal breeding. Commonly used models include SNP BLUP with extensions (BayesA, etc), genomic BLUP (GBLUP) and single-step GBLUP (ssGBLUP). These models
