Relationship coefficient - ANSWERSEstimated fraction of genes that are the same due to ancestry
Rxy=(CovXY)\sqrt((1+Fx)(1+Fy))
Inbreeding - ANSWERSIncreases shared genes and homozygosity
And animal is inbred if its parents are related
Why do inbred animals tend to be more genetically similar? - ANSWERSSince inbreeding increases
homozygosity, an inbred animal will pass down the same allele to its offspring
Progeny testing - ANSWERSTest for a recessive gene; a phenotypically dominant animal (X) that could be
homozygous dominant is mated to animals that could produce homozygous recessive offspring if M is a
heterozygote. 2 possible outcomes:
1. One or more homozygous recessive offspring: X has 0 probability of being homozygous dominant
2. All offspring are phenotypically dominant: probability of X being homozygous dominant increases,
based on LoC
Inbreeding coefficient (Fx) - ANSWERSEstimated fraction of gene pairs that are homozygous due to
inbreeding
If parents of X are W and Z...
Fx=1/2*CovWZ
Level of Confidence - ANSWERSProbability of detection, and measure of how good the test is
PAA,PAa, Paa= prob that a mate is homo dom., hetero, or homo rec.
Probability of homozygous dominant - ANSWERSPo=(1+Ps+Pd+Psd)/(3+Ps+Pd-Psd)
After offspring:
P(HD|CT)= Po/(1-(LoC(1-Po))
Hog color genetics - ANSWERS4 primary genes:
I-> white, IL= white belt, i=base color
K= normal, kk= six white points
E=black, EP=black spots on base color, e=non-black
DD= white/off white, Dd=sandy, dd=red
Blue butt - ANSWERSE_ __ __ IIL or E_ __ __ Ii
White with dark skin spots (hog color) - ANSWERSEp/e_DD__IL or Ii
White with red tint and few dark skin spots (hog color) - ANSWERSEp/e_ _d __ IL or Ii
Completely white (hog color) - ANSWERSII
