Epigenetics- Comparing Identical Twins
Does your DNA control you or can you control your DNA? Epigenetics is a new area of science that studies how environmental factors affect gene expression. In this activity students will pair up with an "identical twin" and see how decisions they make throughout their life affect which genes are turned on or off.
Genetics Lab: Effect Of Environment On Gene Expression
Biology Lab: Effect Of Environment On Gene Expression. This lab demonstrates that the phenotype of an organism is due not only to its genotype, but also to the conditions in the surrounding environment. An individual's phenotype often depends on the influences of the environment. $

10 Fun Ways To Reduce Your #Cortisol Levels - The body knows how to heal itself. they are beautifully equipped with natural self-repair mechanisms that fight cancer, prevent infection, repair wounds, protect us from infectious agents and foreign bodies, and even affect how our genes express themselves! But here’s what most people don’t know. These natural self-repair mechanisms get deactivated when your body is full of stress hormones like cortisol and epinephrine in “fight-or-flight” mode.
Heredity: Crash Course Biology #9
▶ Heredity: Crash Course Biology Module 7, CH 8 10:18 Mendelism, in a chromosome there is a Gene is a scection of DNA that contains info that determines a trait/phenotype (physical appearance). Polygenic trait=many genes deciding how physical traits are expressed. Pleiotropic=single genes deciding how multiple genes expressed. This is called a Mendelian trait. Dominance is when one allele totally masks or suppresses the expression of the other parents recessive allele.
