This document contains slides from genetics classes discussing concepts like monohybrid and dihybrid crosses, Punnett squares, dominant and recessive traits, and sex-linked traits. Openers ask students to complete Punnett squares and describe crosses between individuals with different genotypes. The slides cover topics like Gregor Mendel's experiments, human genetic traits, pedigrees, and reviewing key genetics terms and concepts.
