Quiz 11

Question 1

Heritability

Answer 1

a measure of the strength of the relationship between performance and breeding values for a trait in a population

Question 2

Highly heritable

Answer 2

if the offspring resemble their parents closely for a trait

Question 3

Lowly heritable

Answer 3

if the offspring do not resemble their parents for a trait

Question 4

Highly correlated

Answer 4

phenotype is a good predictor of breeding value (closer to 1)

Question 5

Lowly correlated

Answer 5

phenotype is a poor predictor of the breeding value (further from 1)

Question 6

Environmental uniformity

Answer 6

manage animals so that environmental affects on the performance of different animals are as similar as possible

Question 7

Accurate measurement of performance

Answer 7

the more accurate measurement of performance in a trait, the higher the h^2

Question 8

Mathematical adjustments for known environmental effects

Answer 8

adjust of weaning weight to a 205-day

Question 9

Trait ratio

Answer 9

an expression of relative performance

Question 10

Repeatability

Answer 10

a measure of the strength of the relationship between repeated phenotypic values for a trait in a population

Question 11

Producing ability

Answer 11

the value of an animal as a producer for any repeated trait

Question 12

Most probably producing ability (MPPA)

Answer 12

is an estimate of producing ability
