Laws of Inheritance ​
Discovered by Mendel
Law of dominance ​
An organism with at least one dominant allele displays the effect of the dominant allele.
Law of segregation ​
During gamete formation, the alleles for each gene segregate from each other so that each gamete only carries one allele for each gene.
Law of independent assortment ​
Genes of different traits segregate independently.
Patterns ​
Epistasis ​
Expression of a gene that alters that of a different gene
[!example] Gene for coat colour in Labrador retrievers affect the gene for deposition of pigment into hair.
Pleiotropy ​
Expression of one gene on multiple characters
Inverse of polygenic inheritance
[!example] Albinism
Polygenic inheritance ​
Expression of multiple genes on one character
Inverse of pleiotropy
[!example] Skin colour is determined by multiple genes.
