Question 34

A gene in a population of snails exists as five different alleles. How many of them can one snail carry?

  1. One of them, chosen at random
  2. All five of them, one after another
  3. Five, because the population has five
  4. Two of them, one on each chromosome of the pairCorrect answer

A snail has one copy of the gene on each chromosome of a pair, so there are exactly two slots no matter how many forms exist in the population. The larger figure describes the variety available across all the snails together, which no single snail can hold at one time.
