
autosomal dominant traits
Genetic Diseases: Huntingtons, achondroplasia, etc.

sex-linked traits (colorblindness, hemophilia)
sex-influenced traits (pattern-baldness)
Punnett square problems
Morgan's Drosophila studies
Sutton's "Chromosomal Theory of Heredity"
Multiple alleles, with Codominance (blood types); Punnett square problems
TEST- Genetics word problems, probability and Punnett squares
Exceptions to Punnett probabilities, or "Weird Things That Chromosomes Do"

