Substoichiometric Shifting Is Accompanied by the Loss of Reciprocal Recombination Products.
(A) Detection of the reciprocal recombination product RA2 (bottom panel) in the progeny of a T4 plant that shows partial mtDNA shifting (stage I; top panel).
(B) The same as (A), in the progeny of a plant that has a complete mtDNA shift (stage II).
