DESCRIBE THE STAGES INVOLVED IN THE SEXUAL REPRODUCTION OF A ZYGOSPORE (DIAGRAM)

  1. Occurs between + strain and - strain. When hyphae of opposite strains grow close together, swellings form on both strains and touch each other
  2. Nuclei from both hyphae move into these swellings which are now called progametangia
  3. cross walls form to produce gametangia
  4. The walls of the gametangia dissolve and... (More)
