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

In goats, a beard is produced by an autosomal allele that is dominant in males and recessive in females. We’ll use the symbol Bb for the beard allele and B for the beardless allele. Another independently assorting autosomal allele that produces a black coat (W) is dominant over the allele for white coat (w). A cross allowed between BBbWw (male) X BBbWw (female). What is proportional of female progeny will beard with black coat?
