A model for calculating the distribution of recurrent parent chromosomal segments in each generation. The more chromosomal segments, the fewer individuals there will be at the extremes of the distribution. The frequency distribution of recurrent parent genomic segments is skewed toward the recurrent parent in each successive generation. Effects of selection on genome content 7. A. Background E - Lycopersicon esculentum cv.
Parents differ greatly w.r.t.
It's very important, in identifying QTL's, to start with two parents on the extrema of the distribution. Both are polymorphic for genes affecting fruit pH , which is important for the optimal preservation of tomato products . 20 cM apart C. Molecular markers segregate according to Mendelian expectations during backcrossing 1. These expectations were confirmed as shown in Fig. 2. These results help validate the approach, because they demonstrate that markers segregate according to Mendelian principles.
