  • The cortical pattern mutant broadened cortical domains (bcd) in Tetrahymena thermophila is unable to complete the nuclear events associated with conjugation. bcd x bcd pairs become arrested at the "nuclear exchange" configuration. Genetic analysis reveals that the bcd conjugal block is 100% penetrant, under macronuclear control, and rescueable (a) by outcrossing to a wild-type partner, (b) by administration of a hyperosmotic shock 5 hr after cells are mixed for mating, or (c) by cytoplasmic… CONTINUE READING
