Multiple Choice

Why is DNA important?

• it is very small and very complicated
• it's in everything
• it serves as the blueprint for traits of all living things
• because we eat it every day for energy

Multiple Choice

What is the difference between genotype and phenotype in genetics?

• Genotype refers to physical traits, phenotype refers to genetic makeup

• Genotype refers to genetic makeup, phenotype refers to physical traits

• Genotype and phenotype mean the same thing

• Genotype refers to dominant traits only, phenotype refers to recessive traits only

Multiple Choice
