Study Notes
Study Notes
- Students should know how to complete Punnett squares, including genotype, phenotype, and probability.
- Students should know how to complete pedigrees, including 2 or 3 generations, proper shading, and labeling.
- When flipping a coin, the probability of it landing on tails is 50%.
- Gregor Mendel's contributions to genetics include his study of genetics in organisms.
- Gregor Mendel's principles of genetics apply to all organisms.
- All organisms have chromosomes that determine sex: females have XX, males have XY. Egg cells carry an X chromosome, and sperm cells carry either an X or Y chromosome.
- Genetic disorders can be dominant, recessive, or sex-linked.
- Examples of genetic disorders include cystic fibrosis, sickle cell anemia, Tay-Sachs disease, and albinism, Huntington's disease, Achondroplasia (a form of dwarfism), Hemophilia (X-linked recessive), and color blindness.
