WebInheritance is the transmission of traits or information from one generation of individuals or cells to the next. Inheritance can occur via two different overall mechanisms—genetic inheritance or epigenetic inheritance. Genetic inheritance refers to the transmission of the genomic sequence on the basis of DNA replication.
