Overall Summary

See Kramer, H.H., and Burnham. 1947. Genetics 32:379-390.

1. For testcross data, use direct calculation of percent recombination in the total population. Immer and Henderson (1943) provide the standard error of p.
   
   
2. For F₂ coupling or repulsion data alone, use the product method. See Immer and Henderson (1943) for s.e.(p).
   
   
3. For F₃ data from doubly dominant F₂ phenotypes, the maximum likelihood method must be used as described by Immer and Henderson (1943).
   
   
4. For combined data from F₂ repulsion and coupling data with F₃ progeny test, use Fisher's scoring method.
