# Inheritance --- **Inheritance** is a cornerstone concept in [[genetics]] that describes how [[gene|genes]] are passed down through generations. >[!theory] >The **Chromosome Theory of Inheritance** states that specific [[gene|genes]] are found on specific [[chromosome|chromosomes]], and transmission of chromosomes to daughter cells at [[meiosis]] explains why genes are inherited according to [[inheritance|Mendel's Laws]]. ## Types of Inheritance **Autosomal inheritance** describes patterns of inheritance where genes are located on [[chromosome|autosomes]]. **X-linked inheritance**, or "sex linked" describes patters of inheritance where genese are located on the [[chromosome|sex chromosomes]] - If the gene is on the X chromosome it is **X-linked inheritance**. - If the gene is on the Y chromosome it is **Y-linked inheritance**. **Epigenetic inheritance** is the collective term for any mechanism of inheritance that is due to something *other* than differences in [[DNA]]. For example, in eukaryotes a skin cell and a liver cell both have the same genes, but one becomes skin and the other, liver. Another example is when prenatal conditions have lasting effects on the offspring. ___
