#7 Vítejte ve světě epigenetiky!
<p>Dá se zdědit víc, než je zapsáno v genech? Vítejte ve světě epigenetiky! </p><p>Podíváme se, jak prostředí a zážitky rodičů ovlivňují to, jaký bude jejich potomek, co pro vývoj štěněte znamená prenatální stres, a jak nám epigenetika může rozšířit pohled na dovoz psů, množírny i vlastnosti, které štěně zdědí po pracovních rodičích.</p><p><br></p><p>Zdroje: </p><p>1) Alberts B., Johnson A., Lewis J., Raff M., Roberts K., Walter P.
