Q1. Bacteria – a single, circular chromosome (usually) Eukaryotes, one complete set of nuclear chromosomes Note that Eukaryotes also possess a mitochondrial genome thus plants have a chloroplast genome and a mitochondrial genome What about fungi? What is the source of those organellar genomes?

Q2. We estimate the size of a population of small mice in a particular field by the mark-recapture method. Our estimate is 350. afterwards, we learn from experiments on the behaviour of these mice that we can locate a baited trap faster if they have already been rewarded with food by visiting that trap once before. Does this mean that our original of 350 individuals was too low or too high? Explain the answer in terms of the principle that underlies the mark-recapture method.
