Quiz 10 Flashcards
Covariation
how two traits or values vary together in a population
Correlation
measure if the strength of the relationship between two variables
Phenotypic
measure of the strength of the relationship between performance in once trait and performance in another
Genetic
measure of the strength of the relationship breeding values for one trait and breeding values for another
Environmental
measure of the strength of the relationship between environmental effects on one trait and environmental effects on another trait
Types of Correlations(3)
phenotypic
genetic
environmental
Measures of Covariation(3)
covariance
correlation
regression
Regression
average change in one variable per unit change in another
True value
unknown attribute that affects animal performance
Predicted value
prediction of a true value
Prediction equation
mathematical equation used to calculate a predicted value based on phenotypic data
Heritability
a measure of the strength of the relationship between performance and breeding values for a trait in a population
Two types of Heritability
heritability in the broad sense
heritability in the narrow sense
