Here are some of the deviations from Mendel’s law of heredity in short:
- Multiple alleles: A gene can have more than two alleles, which means that there are more than two possible phenotypes for that trait.
- Incomplete dominance: This is when the two alleles of a gene do not completely mask each other, resulting in a phenotype that is intermediate between the two.
- Codominance: This is when both alleles of a gene are expressed in the phenotype.
- Polygenic inheritance: This is when a single trait is controlled by multiple genes.
- Linkage: This is when two genes are located on the same chromosome and are therefore inherited together.
