  16. Parentals > non-parentals = linkage Linkage is calculated as the total non-parental types/ total population size 12/94 = 12.7% recombination (13.1 Kosambi cM; 14.7 Haldane cM)

  18. Goal: 2 row, waxy, hulled, short awn VVwwNNll Independent assortment due to crossovers between loci on same chromosome - wwNN The Chi-square test for linkage is Prob( X^2 >= 7.86 | Degrees of Freedom=3 ) <= 0.048995 Accept or reject? Evidence for very weak linkage – see lab example
