Nold AS101 Exam 4

A combination of the genotype and environment

Phenotype is controlled by:

Expected Progeny Difference

The amount that the average offspring of an animal is expected to perform above the average of the population is the _____ for that animal.

Environmental Factors

Which off the following is NOT a factor that affects the amount of genetic change that can be made per year?

Heterozygous Black

Given that black is dominant to red, if a homozygous black male is mated to a homozygous red female all the offspring will be:

Complement strengths of different breeds and increase heterosis

Two main reasons for crossbreeding are:

Currently one of our best tools available for genetic selection

The amount by which the average offspring of the animal is expected to exceed the average of the population

Used to compare genetic potential

An expected progeny difference (EPD) is:

Rib eye area

In which of the following traits would you expect to make the fastest genetic progress?

Heritability

The percent of the phenotypic variation that is due to genetics and that can be passed from parents to offspring is:

Heterosis- hybrid vigor

If you mate a bull from whom you expect 600lb. average weaning weight claves to cows that average 400lb. weaning weight calves, et the calves average a 540 lb. weaning weight, the additional 40 lbs. over the average of the parents is due to:

That are “post selection” e.g. carcass quality and palatability

DNA testing has the most potential benefit for producers with traits:
