Table 2 Expected genotype frequencies in the crossbred offspring when individuals from lines \({A}\) and \({B}\) are mated at random to each other

From: Comparison of linkage disequilibrium estimated from genotypes versus haplotypes for crossbred populations

Line \({A}\) haplotype Line \({B}\) haplotype
\(00\,{r}{^{\prime}}\) 01 \({s}{^{\prime}}\) \(10\,{t}{^{\prime}}\) \(11\,{u}{^{\prime}}\)
\(00\) \(r\)a \(\frac{00}{00}{{r}^{\prime}r}^{\mathrm{b}}\) \(\frac{00}{01}s{^{\prime}}r\) \(\frac{00}{10}{t}{^{\prime}}r\) \(\frac{00}{11}{u}{^{\prime}}r\)
\(01\,s\) \(\frac{01}{00}r{^{\prime}}s\) \(\frac{01}{01}s{^{\prime}}s\) \(\frac{01}{10}{t}{^{\prime}}s\) \(\frac{01}{11}{u}{^{\prime}}s\)
\(10\,t\) \(\frac{10}{00}r{^{\prime}}t\) \(\frac{10}{01}s{^{\prime}}t\) \(\frac{10}{10}{t}{^{\prime}}t\) \(\frac{10}{11}u{^{\prime}}t\)
\(11\,u\) \(\frac{11}{00}r{^{\prime}}u\) \(\frac{11}{01}s{^{\prime}}u\) \(\frac{11}{10}{t}{^{\prime}}u\) \(\frac{11}{11}u{^{\prime}}u\)
  1. aMarginal frequencies are haplotype frequencies
  2. bJoint frequencies are the genotype frequencies
