Document Summary
Consisted of identifying all 30,000 genes in our chromosomes. Influenced by many genes as well as the environment (eg. height, iq, personality, etc. ) Effects of genes and environment: twin studies i. ii. Identical twins share the same genes, fraternal only 50% Identical twins reared together share genes and environment iii. *assumption of random mating: if people choose mates similar to themselves, the dz twins may share more than 50% of their genes. Molecular genetics: classical twin study designs are only one aspect of this research, twin studies estimate the heritability of a trait. Love smell: males wore the same shirt for two nights, women smelled them. Genes and evolution at work on the brain. Dna: proteins: chromosomes: genotype: phenotype: allele: homozygous: heterozygous: Each cell in our bodies contains an entire set of our dna. True or false? not influenced by his genetics. Paul"s personality is a product of the environment he was raised in and is.
