Rate of Genetic Change Flashcards
1
Q
factors of genetic selection
A
selection accuracy
selection intensity
genetic variation
generation interval
2
Q
rate of change
A
ΔBV/t
3
Q
selection accuracy
A
accuracy of breeding value prediction
correlation of predicted and actual breeding value
^
rBV,BV
4
Q
selection intensity
A
how choosy management is
high intensity: selecting very best
low intensity: selecting randomly
i = (SCs - SC) / σsc
5
Q
genetic variation
A
variability of BV in a population
σBV
6
Q
generation interval
A
amount of time to replace a generation
^
ΔBV/t = (rBV,BV i σBV) / L
