The document discusses basic genetics concepts including:
- Gregor Mendel studied heredity through pea plant experiments in the 1800s.
- Mendel observed that traits separated and recombined when parent plants differing in one trait were crossed.
- Terms like dominant, recessive, genotype and phenotype were introduced to explain his findings.
- The Punnett square was developed as a tool to predict potential offspring of crosses.

13. Practice-Monohybrid Crosses A child is diagnosed with a recessive genetic disease. Neither parent has the disease. What are the genotypes of the parents? Phenotypes: Genotypes: N ? ? nn N
