Short communication: genomic kinship, opposing homozygotes and genetic diversity in a selected population of Australian Angus cattle.

ABSTRACT: Using molecular genotypes to check for Mendelian inconsistencies allows the identification of animals for which pedigree and genotype information disagree. A further use of molecular data is to understand and manage genetic diversity in a population. We sourced from the Angus Australia database a selected population of 11,224 animals, including 10,309 progeny born between 2013 and 2023 from 269 sires and 646 dams with at least 100 and 10 progeny, respectively. All animals had imputed genotypes for 61,105 autosomal markers. The additive and dominance genomic relationship (GR), as well as the number of opposing homozygotes (OH) were examined for pedigree-based relationship pairs including parent-offspring (PO; 21,307 pairs), full-sibs (FS; 35,486), half-sibs (HS; 677,421), grandparent-grando
