Deaminases increase spore viability after meiosis. (A) Ascus dissection analysis: relative viabilities of rec12Δ single spores from tetrads, triads, and dyads in control-transfected cells (white), in AID catalytic mutant expressing cells (orange), and in catalytically active AID expressing cells (red). The numbers of the spores that were isolated are indicated at the bottom of each column, and the viability of the vector-only rec12Δ strain was set to one. (B) Percentage of viability of random spore analysis, from rec12Δ cells expressing different deaminases during meiosis.
