Concept 31.2

Q1: In terms of haploidy versus diploidy, how do the life cycles of humans and fungi differ?

A1: Majority of human life cycles are dominated by dipoid stages while in fungi, majority consists of haploid stages.

Q2: Suppose that you sample the DNA of two mushrooms on opposite sides of your yard and find that they are identical. What are two hypotheses that could reasonably account for this result?

A2: The 2 mushrooms might be reporoductive structures of the same mycelium. Or they might be parts of 2 separate organisms that have arised from a single organism through asexual reproduction and thus carry the same genetic information.
