A locus and B locus are in Linkage Disequilibrium D = f(AB) x f(ab) - f(Ab) x f(aB) Maximum with no recombination D -> 0 with free recombination (linkage equilibrium) When allele frequencies are intermediate: f(A) = f(a) = f(B) = f(b) = 0.5, and maximal LD occurs so t...
50% would be recombinant. These genes are linked, with 24.3% recombination between the P gene and the L gene. If the genes were right on top of each other, that is, the two

This is because the reassortment and recombination of different alleles in the offspring population could produce a range of phenotypic values48. As the QTL tracked in this study could only explain up to 37.0% and 37.9% of phenotypic variation for resist- ance and survival time (Tables 2 ...

In order to investigate population-specific recombination processes we studied the rate of LD decay within the populations of different origin (Figure5Band5C). Due to the limited number of lines, WB, KS and NY winter wheat and WA spring wheat populations were excluded from this analysis. As ex...
Recombination is Reciprocal Chromatids that do not cross over are called “parental” or “nonrecombinant” Chromatids that do cross over are called “recombinant” The recombinant gametes can never be more than 50% of the total A. Yellow body (y) and white eye (w) recessive, X- linked ...
