Document Summary

Sickle-cell anemia: red blood cells turn into crescent shape instead of round. Clogs blood vessels, block blood flow = high fever, severe pain, swelling and tissue damage due to lack of blood flow. Carrying allele gives advantage of malaria carrying both is bad. In united states malaria is rare no benefit from csa cell. Dna: helix-shaped molecule made up of nucleotide base pairs. Diathesis-stress: have genetic weakness of something more likely to develop it. Recessive: need two copies to get phenotype. Dominant: need one copy to get phenotype. Most traits are polygenic: controlled by more than one gene. Range of reaction: genes set boundaries within which we can operate. Interaction between environment and genes sets the point where we fall on the range. Nutrition skinny or fat /tall or shirt. Genetic environmental correlation: genes influences our environment and environment influences expression of genes. Ex. mom is soccer player and dad musician more likely to be exposed to those things.
