Question

1. Which would not be considered a part of an effective animal breeding program?

Providing optimum feed for the desired outcome (growth, milk)

Selection for specific traits for that breed

Selecting the appropriate sire or dam

Targeting the right market

Selection for mating based on a good feeling for the animal

2. A decrease in generation interval usually causes?

A decrease in accuracy of selection

An increase in collected records

A decrease in the rate of genetic change

An increase in selection intensity for females

A decrease in genetic variation

3.An increase in accuracy of selection most likely means

Few records are available

There is a relationship between true breeding value and heritability

The rate of genetic change will be slowed

There is an increase in generation interval

The selection intensity is decreased

4.Which is a true statement about accuracy of BV prediction?

With enough progeny, accuracy is high even when heritability is low

Performance records on relatives are most valuable when heritability is high

The individuals performance is most valuable when heritability is low

5. Which statement is true about regressing for amount of information?

Results in the calculation of true values

Is done by hand calculations when using BLUP

Causes genetic predictions to be more conservative

Requires the use of a formula for calculating a correlation

Results in biased genetic predictions

Records on half-sibs are more valuable than progeny records

Progeny records are less important than the individual (self)
