EVOLUTION AND GENETICS
Essential Questions:
- Why do some human traits show a large variety of phenotypes?
- Why are some sex-linked traits more common in males than in females?
- How do geneticists use pedigree charts?
Skills:
Students will be able to:
- Debate whether natural selection, intelligent design, or Lamarckianism best fit their understanding of evolution.
- Explain genetic variation.
- Perform a pedigree chart.

Which of the following statements is NOT a description of the role of genes in
heredity?
A) Mutations in DNA patterns result in variations of genes and traits.
B) No two genes are alike and account for the many differences between
organisms.
C) Parents can select the most favorable genes to be passed on to their
offspring.
D) Genes contain the units of information that determine traits passed on to
offspring.
