Kinship matrix dendrogram for the Arabidopsis mapping population.

Dendrogram of the EMMA kinship matrix for selected Arabidopsis thaliana accessions used for GWA mapping. Accessions were filtered for common flowering time (63.1 ± 0.95 (s.e.) days to flowering) to reduce effects from ontogeny. These accessions fall into approximately five major groups (I-V) as illustrated.用于全基因组关联作图（Genome-Wide Association mapping, GWA）的选定拟南芥（Arabidopsis thaliana）种质的EMMA亲缘关系矩阵树状图。为削弱个体发育效应的干扰，研究人员对供试种质的开花时间进行筛选，使其开花天数统一为63.1±0.95（标准误，standard error, s.e.）天。如本图所示，这些供试种质可划分为约五个主要类群（I-V）。
