Estimation of number of sub-populations (K) in synthetic hexaploid wheat based on unlinked SNP markers.
a) Population structure of synthetic hexaploid wheats. The genotype of each line on the figure is represented by a colored line where each color reflects the membership of a cultivar in one of the K clusters. The proportion of the colored segment indicates the proportion of the genome drawn from the K clusters. b) The log probability of data as a function of K for unlinked SNP markers. Means log probability of data Ln P (D) for each value of K were calculated from 10 independent runs of structure. c) Estimation of number of sub-populations (K) in synthetic hexaploids using deltaK values.

Figure 3.
Linkage disequilibrium (LD) decay as a function of genetic distance.
LOESS curve was fitted by robust locally fitted regression and shows that LD decays with genetic map distance and dashed line indicates the derived threshold for LD due to linkage.
