He went on to cross pea varieties that differed in six other qualitative traits.
2.
Gene maps or Qualitative Trait Loci ( QTL ) maps can be produced using two separate methods.
3.
Qualitative traits ( requires less that 2 genes ) such as color, can be identified using MAS ( marker assisted selection ).
4.
This specification involves the same number of right-side variables as does the previous specification with an interaction term, and the regression results for the predicted value of the dependent variable contingent on X i, for any combination of qualitative traits, are identical between this specification and the interaction specification.
