Study Notes
Study Notes
- Understand how to construct Punnett Squares, including genotype, phenotype, and probability.
- Know how to interpret and create pedigrees, focusing on 2 or 3 generations, with proper shading and labeling.
- When flipping a coin, the probability of tails is 50%.
- Gregor Mendel's significant contribution to the study of genetics.
- Understand Mendel's principles of genetics and how they apply to all organisms.
- Chromosomes determine gender: females (XX) and males (XY).
- Different types of genetic disorders exist: dominant, recessive, and sex-linked.
- Examples of sex-linked disorders include cystic fibrosis, sickle cell anemia, Tay-Sachs disease, and albinism.
- Other examples of genetic disorders include Huntington's disease, achondroplasia (a form of dwarfism), and color blindness.
- Hemophilia is an X-linked recessive disorder.
