1

Genetic prediction simply refers to...

estimation of breeding values (BV)
progeny differences (PD)
producing abilities (PA)

2

To predict a value (EBV, MPPV, etc.), we need:

regression coefficient(s)
phenotypic values (performance records)
means (averages)

3

BLUP (best linear unbiased prediction)

a method of genetic prediction that is particularly appropriate when performance come from genetically diverse contemporary groups

4

Statistical model

a mathematical representation of animal performance

5

Animal model

an advanced statistical model for genetic prediction that is issued for all animals in a population

6

Field data

information that is reported by producers to government agencies for use in genetic prediction

7

EPD (expected progeny difference)

expected difference between the mean performance of the individual's progeny and the mean performance of all progeny

8

Types of EPDs (4)

1. parent EPD: an EPD for an animal with progeny data
2. non-parent EPD: an EPD for an animal without progeny data
3. interim EPD: an updated EPD calculated between BLUP analyses that incorporated new information
4. pedigree EPD: an EPD based only on pedigree data

9

ACC (accuracy)

correlation between the estimated and the true unknown value

10

PC (possible change)

indicates the potential amount of change in a prediction
