Types of Inheritance: Beyond Mendel's Rules
What are some examples of inheritance types that do not follow Mendel's rules?
1. Inheritance due to incomplete dominance
2. Inheritance due to codominance
3. Inheritance of traits controlled by multiple genes
Examples of Inheritance Types Beyond Mendel's Rules
One situation that is NOT an exception to Mendel's rules is the inheritance of traits controlled by multiple genes. Mendel's laws, such as the law of segregation and the law of independent assortment, still apply to these traits.
Since Mendel's time, types of inheritance that don't follow Mendel's rules have been discovered. However, the inheritance of traits controlled by multiple genes is not an exception to Mendel's rules.
Mendel's laws of inheritance, including the law of segregation and the law of independent assortment, are still applicable to traits controlled by multiple genes. These traits exhibit continuous variation and are known as polygenic traits. For example, human height is controlled by multiple genes, with each gene contributing a small effect to the overall height.
Although the inheritance of polygenic traits may be more complex than simple Mendelian inheritance, it does not contradict Mendel's principles. In conclusion, the inheritance of traits controlled by multiple genes is not an exception to Mendel's rules.
