  • SD, standard deviation; n.d., not determined.

  • a Class 1 = Genes required for zygote formation; Class 2 = Genes required for spores to be iodine-reactive.

  • b The average of at least three experiments. At least 100 cells were counted in each experiment.

  • c The average of at least three experiments. At least 100 asci were counted in each experiment.
