Philippe Bouchet and colleagues conducted a massive survey of marine molluscs on the west coast of New Caledonia. For 20% of the total species that were located and identified, only a single specimen was found. What does that suggest about the diversity of molluscs in this area?

#Unit 9. Diversity of Life Forms
  1. The west coast of New Caledonia is not an appropriate habitat for molluscs.
  2. Many of the species from this 20% are probably rare.
  3. They were not sampling uniformly throughout the area.
  4. Many of the species from this 20% are most likely just dispersing through the are

Mendel crossed tall pea plants with dwarf ones. The F1 plants were all tall. When these F1 plants were selfed to produce F2 generation, he got a 3: 1 tall to dwarf ratio in the offspring. What is the probability that out of three plants (of F2 generation) picked up at random all three would be dwarf?
