Lesson 3: DNA's Role in Determining Your Traits
                 Practice Test
Question 1:
All genes have ______
  A.At least one allele
  B.Multiple alleles
Question 2:
The existence of multiple alleles of a particular gene
  A.Always results in mutation of the                 genome
  B.Indicates that multiple phenotypes               may be possible
  C.Indicates a high SNP frequency in               the gene
   D.Increases the penetrance of the               alleles
Question 3:
The higher the penetrance of an allele
  A.The more common it is among               people
  B.The more variation it has in its             sequence
  C.The more likely it is to result in a               variant trait
  D.The more likely it is to result in a             favorable trait
