#Unit 8. Inheritance Biology

Early in the development of a plant, a mutation in cpDNA removes a specific BgIII restriction site (B) In this species cpDNA is inherited maternally. Seeds from the plant are grown, and the resulting progeny plants are sampled for cpDNA. The cpDNAs are cut with BgIII, and Southern blots are hybridized with the probe P shown. The autoradiograms show three patterns of hybridization:
