Theoretical aspects of crossbreeding [PDF]
Genetics Selection Evolution, 1971 SUMMARY Methods of utilising breeds and bleed crosses in animal production are discussed, taking account of both genetical and economic aspects. The theoretical principles for breed and breed cross comparison are analysed, but most emphasis is given to methods of improvement of existing crosses.

Characterization of Autozygosity in Pigs in Three-Way Crossbreeding
Frontiers in Genetics, 2021 Crossbreeding in livestock can be used to increase genetic diversity. The resulting increase in variability is related to the heterozygosity of the crossbred animal. The evolution of diversity during crossbreeding can be assessed using genomic data.

"You could get the best of both breeds or the worst of both": UK public attitudes towards crossbreeding in dogs - with a specific focus on brachycephalic dogs. [PDF]
PLoS ONEExtreme conformation and reduced genetic diversity are recognised to lead to severely reduced health, welfare and longevity in certain dog breeds. There is growing interest in applying strategic crossbreeding to promote more moderate conformations and ...

Smallholder experiences with dairy cattle crossbreeding in the tropics: from introduction to impact
Animal, 2015 Crossbreeding of indigenous tropical and improved western dairy cattle breeds as tool to improve dairy cattle performance on smallholder farms has been widely advocated, criticised and yet applied. The government of Ethiopia supported this technology for

Crossbreeding in Random Forest
CoRR, 2021 Ensemble learning methods are designed to benefit from multiple learning algorithms for better predictive performance. The tradeoff of this improved performance is slower speed and larger size of ensemble learning systems compared to single learning systems.

Breed of origin of alleles and genomic predictions for crossbred dairy cows
Genetics Selection Evolution, 2021 Background In dairy cattle, genomic selection has been implemented successfully for purebred populations, but, to date, genomic estimated breeding values (GEBV) for crossbred cows are rarely available, although they are valuable for rotational ...
