Lesson 3: DNA's Role in Determining Your Traits
Reading Lesson 3 Practice Test

Upon completion of this lesson, you will be able to:

  • Recognize that both genes and environment play a role in defining a person's traits
  • Recall that most human DNA sequence variation is in the form of single nucleotide polymorphisms (SNPs)
  • Explain the relationship among genes, alleles, genotypes, and phenotypes
  • Explain that variations in DNA sequence result in different versions of genes within the human population
  • Match vocabulary words to their definitions, including trait, allele, genotype, phenotype, single nucleotide polymorphism (SNP), genetic potential, and penetrance
