|
selection objective
|
trait/character that you are trying to improve by selection (eg - greater milk yield)
|
|
|
selection criteria
|
trait that is actually measured (eg - litres milk yield in 305 day lactation)
|
|
|
selection index
|
aggregate of multiple selection criteria weighted according to relative importance
|
|
|
repeatability
|
variation in the magnitude of one trait at two different measurements
|
|
|
heritability
|
proportion of phenotypic variation that can be explained due to genetic variation
|
|
|
breeding value
|
the additive genetic value; sum of the average gene effects
|
|
|
genetic correlation
|
the value of one trait can be reliably predicted from another
|
|
|
effective population size
|
population size accounting for the fact that not all members will contribute the same proportion of gametes to the next generation
|
|
|
generation interval
|
average age of parents when offspring are born
|
|
|
selection intensity
|
superiority of selected parents in relation to the amount of trait variability in the entire population
