Question

Give any two difference between homothallism and heterothallism.

Answer 1

• Homothallism refers to a condition where hyphae are genetically compatible and therefore forming zygospores from two branches of the same mycelium. Whereas, heterothallism refers to a condition where two complementary mating types are needed for sexual reproduction.
  
• In other words, homothallic species produce zygospores independently, whereas heterothallic species require the presence of opposite mating types.
• Homothallic are self sterile whereas Heterothallic are not self sterile.
