Genetsko in negenetsko dedovanje

Globočnik, Gašper (author), Malovrh, Špela (mentor)

Pojem dedovanja se je s prenosa genov iz generacije v generacijo razširil na prenos tudi negenetskih informacij, tako vertikalno med generacijama kot horizontalno med sovrstniki. Naslednja generacija od staršev poleg genetskih podeduje tudi številne negenetske dejavnike, med katerimi so epigenetske spremembe, mikrobiota, ekološke spremembe ter obnašanje. Tako genetski kot negenetski dejavniki se izkazujejo kot del fenotipa, prav tako vplivajo tudi na podobnost med osebki. Z vplivanjem na genetske in negenetske dejavnike lahko izboljšamo dobrobit in rejo živali.

• Title: Genetic and non-genetic inheritance

Abstract

The concept of inheritance has been expanded to include not only the transmission of genes, but also the transmission of non-genetic information that is inherited not only vertically between generations, but also horizontally between conspecifics. Each generation inherits both genetic information and non-genetic factors from its parents, which include epigenetic factors, microbiota, ecological changes, and behaviour. Both genetic and non-genetic factors contribute to phenotypic resemblance between individuals, parents and offspring and contribute to phenotypic stability across generations. If we consider the non-genetic factors, we could also improve animal husbandry and welfare.
