The regular alternation, in the life cycle of haplontic, diplontic and diplohaplontic organisms, of meiosis and fertilization which provides for the production offspring. In diplontic organisms there is a life cycle in which the products of meiosis behave directly as gametes, fusing to form a zygote from which the diploid, or sexually reproductive polyploid, adult organism will develop. In diplohaplontic organisms a haploid phase (gametophyte) exists in the life cycle between meiosis and fertilization (e.g. higher plants, many algae and Fungi); the products of meiosis are spores that develop as haploid individuals from which haploid gametes develop to form a diploid zygote; diplohaplontic organisms show an alternation of haploid and diploid generations. In haplontic organisms meiosis occurs in the zygote, giving rise to four haploid cells (e.g. many algae and protozoa), only the zygote is diploid and this may form a resistant spore, tiding organisms over hard times. The union or introduction of genetic information from compatible mating types that results in a genetically different individual. Conjugation requires direct cellular contact between the organisms. The process by which a cell decreases the rate or frequency of the initiation of conjugation with cellular fusion. Any process that stops, prevents or reduces the frequency, rate or extent of a multi-organism process, a process by which an organism has an effect on another organism of the same or different species. Any process that decreases the rate of conjugation. Any process that modulates the rate or frequency of conjugation, the union or introduction of genetic information from compatible mating types that results in a genetically different individual. Any process that modulates the rate or frequency of conjugation with cellular fusion. A conjugation process that results in the union of cellular and genetic information from compatible mating types. An example of this process is found in Saccharomyces cerevisiae. Any process that decreases the rate or frequency of conjugation with cellular fusion.
