breeding exam 3 true and false

true

P = BV + GCV + E

true

effective crossbreeding systems require purebred animals

true

BV represents the part of G that can be passed from parent to offspring

true

breeding value is the sum of independent, additive gene effects that are transmittable to offspring

true

only one of each gene pair can be transmitted from parent to offspring. Genes can't be transmitted in pairs. This explains why independent gene effects, but not gene combination effects, are transmitted from parent to offspring.

true

the biological phenomenon called hybrid vigor is the result of non additive genetic merit

true

environmental effects can be temporary or permanent

true

random drift is the changing of gene frequencies from generation to generation due to purely to chance

true

independent gene effects are known as additive gene effects since the BV for a trait us the sum of the independent gene effects over all loci

true

seedstock breeders sell not only animals, but also information about those animals. The more and better the information, the more valuable the product
