  • Individual progeny were scored as UP+ if they have the drug-resistance phenotype of the plus parent or UP− if they have that of the minus parent (of if they were among the few progeny that were clearly a mixture of sensitive and resistant cells). Zygotes were scored as UP+ if all the individual progeny from that zygote were UP+ , as UP− if all were UP− , and biparental (BP) if there were progeny of both types. Zygotes that are BP or UP− are considered exceptional.

  • a Only zygotes with three or four surviving progeny are included.

  • b Includes five progeny containing both sprr and spr cells.
