 The green alga Chlamydomonas spends most
   of the life cycle in the haploid vegetative phase, asexually producing
   daughter cells by mitosis.

   Unfavorable conditions trigger the sexual phase, where some vegetative
   cells  develop  into  isogametes,  which  can  fuse  to form a diploid
   resistant zygote adapted for surviving harsh conditions.

   When  conditions become suitable again, meiosis of the zygote produces
   two plus mating types and two minus mating types.

   Mitosis of these zoospores returns the cells to vegetative colonies.



 The bread mold Neurospora spends
   most of it life cycle in a multicellular haploid stage.

   Following  fertilization  of  conidia  of  opposite  mating types, the
   zygote undergoes meiosis in an ascus, which retains the haploid tetrad
   (do not confuse with tetrad formed in prophase I).

   Each  cell  in  the  tetrad  undergoes  mitosis  to  produce 8 haploid
   ascospores.

   Because  the 8 cells reflect the sequence of their formation following
   meiosis,  the  tetrad  is  "ordered"  and  can be subjected to ordered
   tetrad analysis.



   In  autogamy  a Paramecium loses the genes from one micronucleus since
   only one of the 8 meiosis products survives.

   A  heterozygous  cell  will  become  a homozygote, and a population of
   heterozygotes  will  produce  a 1:1 ratio of cells homozygous for each
   allele.

0. Four O'Clock plant: bloom afternoon: desert, Mirabilis jalapa tropical South America.
1. flowers different colors; incomplete dominance (codominance)
2. Saccharomyces suppressive: petites have short deletions of mtDNA: replicates more rapidly, or recombination w wild-type mtDNA?
3. cDNA is complementary DNA; chloroplast DNA=cpDNA.
