| Study Outline (See related pages)
- Mendel’s Laws of Inheritance
- Mendel chose pea plants as his experimental organism
- Mendel studied seven traits that bred true
- Mendel followed the outcome of a single trait for two generations
- The 3:1 phenotypic ratio that Mendel observed is consistent with the segregation of genes, now known as Mendel’s law of segregation
- A Punnett square can be used to predict the outcome of crosses
- Mendel also analyzed crosses involving two different traits
- The Punnett square can also be used to solve independent assortment problems
- Modern geneticists are often interested in the relationship between the molecular expression of genes and the outcome of traits
- Pedigree analysis can be used to follow the Mendelian inheritance of traits in humans
- Probability and Statistics
- Probability is the likelihood that an event will occur
- The sum rule can be used to predict the occurrence of mutually exclusive events
- The product rule can be used to predict the probability of independent events
- The binomial expansion equation can be used to predict the probability of an unordered combination of events
- The chi square test can be used to test the validity of a genetic hypothesis
