Study Notes
Modeling Meiosis and Genetic Variation
- Meiosis is a process that can be modeled to demonstrate the creation of new, inheritable genetic variation
- This variation arises through processes such as:
- Independent assortment
- Crossing over
- Random fertilization
- Environmental factors
Modes of Inheritance
- There are different modes of inheritance, including:
- Mendelian
- Non-Mendelian
- Incomplete dominance
- Co-dominance
- X-linked
- Polygenic
- Epistasis
Punnett Squares and Inheritance Probability
- A Punnett square is a tool used to determine the probability of a trait being inherited
- Probability of inheritance can be determined through various inheritance modes
- Meiosis models can be used to show the probability of a trait being inherited
