Table 1 QTL allele frequenciesa and genotypes of individuals in the base outbred lines and their first backcross (BC1) generation

From: Combined detection and introgression of QTL in outbred populations

Allele in outbred lines BC1 genotype

  1. a Subscripts of d and r represent donor and recipient outbred lines, respectively
  2. b Individuals with these genotypes in BC1 generation are informative
  3. The remaining genotype not shown is q r q r , which accounts for all remaining frequencies in backcross generations, e.g. when P(Q d ) = 1.0 and P(Q r ) = 0.0, P(q r q r ) = 1.0 - 0.5 = 0.5
