Question

Base your answers to questions 5 and 6 on

the pedigree chart below, which shows a history of ear lobe shape, and on your knowledge of biology.

Answer 1

Answer: C. ee

Explanation: Since the attached earlobe is a recessive trait, both the e's must be lowercase. Recessive traits must be in pairs to show. The dominant pairs can be represented by EE or Ee. Since the individual being shown is a female with the recessive trait, c is the correct answer.
