Using the Punnet Square, what percent of calves would have horns if a homozygous polled (PP) bull were crossed with a homozygous polled (PP) cow?

• 0

• 25

• 75

• 100

A four-pound ready-to-cook broiler that has all the skin removed, all bones broken, and both wings and the tail missing would be Grade:

• AA

• A

• B

• C

Using the Punnet Square, what percent of the offspring would be black if a white heterozygous (Ww) boar is bred to a white heterozygous (Ww) sow?

• 0

• 25

• 50

• 100

A gene pair that carries two genes for the same trait is:

• blood-typing

• expected progeny difference

• heterozygous

• homozygous

In poultry performance data, a breeding test or a progeny test to determine the ability of a bird to transmit genes for desired characteristics to most of its progeny is an example of:

• future performance.

• past performance.

• present performance.

• rate of gain performance.

If laying hen one has pigment in the vent, hen two in the rear of the shanks, hen three in the front of the shanks, and hen four on the tops of the toes, which hen has been laying the longest?

• One

• Two

• Three

• Four

If black is dominant over red and white faces are dominant over colored faces in cattle, what color offspring would come from crossing a purebred black Angus bull with a purebred white-faced, red Hereford cow?

• Black all over

• Black with white face

• Red all over

• Red with white face

Compared to purebred breeders, commercial livestock producers place more emphasis on:

• breed character.

• color.

• pedigree.

• performance records.

The situation in which one gene does not completely hide the effect of the other gene in a gene pair is:

• dominant

• homozygous

• incomplete dominance

• recessive

If four bulls have the same pedigree and look the same but their Expected Progeny Differences (EPD) for weaning weight are -34.2, -18.0, +10.5, and +36.9, the bull with which EPD should be selected as the sire to most improve the calf weaning weight in the herd?

• -34.2

• -18.0

• +10.5

• +36.9
