Multiple gene inheritance. Sree
Polygenic inheritance is when a trait is influenced by the combined effects of multiple genes, rather than being determined by a single gene. Each gene may have a small additive effect on the phenotype, resulting in a continuous range of phenotypic variations. This type of inheritance is often seen in traits like height, skin color, and intelligence.

Most mutations in eukaryotes exhibit a recessive inheritance pattern because they typically involve changes in a single gene, and the presence of a normal copy of the gene can often mask the effects of the mutated gene. This means that individuals with one normal and one mutated copy of the gene will not show the effects of the mutation, leading to a recessive inheritance pattern.
Dominant Inheritance is when one parent has a dominant gene and the other has a recessive gene. The dominant gene overpowers the recessive gene, and only the dominant gene is phenotypically expressed.Source: http://www.accessexcellence.org/RC/VL/GG/recessive.phpSome examples are variegate porphyria, Huntington's disease and myotonic dystrophy.source: http://genome.wellcome.ac.uk/doc_WTD020849.html
Genomic imprinting is a phenomenon where certain genes are expressed differently depending on whether they are inherited from the mother or the father. This can impact gene expression and inheritance patterns by causing specific genes to be turned on or off based on their parental origin, leading to unique patterns of inheritance and gene expression in offspring.
