Document Summary

Want to be as objective as possible subjectivity leads to a mess. Companion animal: breed or species that doesn"t already have an organized breeding program already in place. Dairy cattle programs ebv calculations, combinations and qtl incorporations are already done for you so not companion animal (no genetic analysis done for breeders, they must do it themselves) Developing a breeding program: base population available, selection goals, phenotypes needed, ebv calculations, ebv combinations, qtl incorporation, select best as parents, breed, get offspring. Regional = small n = inbreeding (f- could be okay or not okay) = sameness (good) Multi birth fewer numbers, more challenging to increase population size increased numbers, so easier to increase population size increase in maternal investment (generation interval increases, gestation increases) Allele and genotype frequencies will remain constant if we have a large, randomly mating population without selection, mutation or migration. Large population; most populations are small or have a small base to start;
