Hungintons, if you have the gene you have the disaese

• folic acid in diet offsets effect of BPA on __ gene
• Behavorial phenotypes, sex orientation, involves both geneitcs and environment
• In Huntington disease, an excess of repeats of a CAG codon on the HTT gene results in the disease. This makes Huntington's disease an example of a CNV condition.

Single Nucleotide Polymprherism (SNPS)

Alleles that differ form each other at separate locations

• risk for Alzheimer's
• APOE
• E2,E3,E4
  Heritability
• Variation in human height across pop. is largely explaiend by genetics
  • dont describe single prson by this
    Epigentics
• Changes in gene expression.
• DNA methalation, adding methaline to end of dna
• Histone added
• Environmental facotrs have the ability to express or not express genes
• stress response
