Document Summary
Mz raised together and dz (dizygotic) raised together: dz share 50% of dna (same as normal siblings) Heritability = (mz same dz same) x2. = ([mz 100g + shared e] ([dz 50g + shared e]) x2. Genes determine reaction to environment: g-e interaction. Environment determines where in range we end up: environment affects children differently (sensitive child vs. energetic child) Environment: poor nutrition: 5"2 , good nutrition: 5"7 . Born to run: discussion: non-generalizable sample, conflict of interest (unethical, making a lot of money from program. Question individuals who are testing the participants. Genes affect the environments we"re exposed to. Traits that appear to be solely due to environment are not: genetic influence is also a part. Parents create environment supportive of reading for child: read to them daily, take them to the library, a lot of books in the home.
