Figure 1.
Individual mtDNAs from P2-line families display multiple RFLPs that differ between sibling plants. mtDNA samples from four siblings (family 4712, lanes 1–4), and from three progeny of the self-pollinated 4712-4 individual (family 96H55, lanes 5–7) were digested with XhoI, and DNA gel blots were hybridized to the cosmid probes N8B1 (left) and N7C9 (right). B37N mtDNA is used for a normal (NB) control.
