Question 57

In a monohybrid Punnett square exercise, a student puts pod colour and plant height into the same four-box square. What is the correct advice?

  1. Use eight boxes in the single square
  2. Draw a separate square for each characteristicCorrect answer
  3. Pick whichever characteristic matters more and drop the other
  4. The square is fine as it is
