title: Sex-limited expression of gene Loci controlling flagellar membrane agglutination in the chlamydomonas mating reaction.
abstract: Mutant strains of Chlamydomonas reinhardi that have lost their ability to undergo sexual agglutination via their flagellar tips have been induced to undergo zygotic cell fusion and meiosis, using a flagellar-directed antiserum. Genetic analysis of antiserum-mediated crosses involving five nonagglutinating mt(+) mutant strains reveals the following: (1) None of the mutations is linked to the mt locus. (2) All of the mutations are "sex-limited," meaning that they can be carried and transmitted by, but not expressed in, mt(-) cells. (3) Four of the mutations (imp-2, imp-5, imp-6, imp-7) are either allelic or closely linked to one another, with imp-8 defining a second locus.
