1
Q

Heritability

A

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

2
Q

Highly heritable

A

if the offspring resemble their parents closely for a trait

3
Q

Lowly heritable

A

if the offspring do not resemble their parents for a trait

4
Q

Highly correlated

A

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

5
Q

Lowly correlated

A

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

6
Q

Environmental uniformity

A

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

7
Q

Accurate measurement of performance

A

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

8
Q

Mathematical adjustments for known environmental effects

A

adjust of weaning weight to a 205-day

9
Q

Trait ratio

A

an expression of relative performance

10
Q

Repeatability

A

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

11
Q

Producing ability

A

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

12
Q

Most probably producing ability (MPPA)

A

is an estimate of producing ability
