1

Heritability

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

2

Highly heritable

if the offspring resemble their parents closely for a trait

3

Lowly heritable

if the offspring do not resemble their parents for a trait

4

Highly correlated

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

5

Lowly correlated

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

6

Environmental uniformity

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

7

Accurate measurement of performance

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

8

Mathematical adjustments for known environmental effects

adjust of weaning weight to a 205-day

9

Trait ratio

an expression of relative performance

10

Repeatability

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

11

Producing ability

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

12

Most probably producing ability (MPPA)

is an estimate of producing ability
