Document Summary

Our nervous system is shaped by our genes and environment. Nurture (environment) everything that affects us from fertilization. Two twins met for the first time at the age of 39, and they were seperated at birth. The two twins were so similar in to many ways. Genotype genes transmitted from parents to offspring cannot change. Phenotype observable traits produced by genotype. Can be altered by expression (or expression) of multiple genes. Composed of dna, heredity blueprint and code for production of proteins (relative expression alter function of cells) Genome full set of chromosomes and associated heritable traits. 46 chromosomes in humans (23 from mom, 23 from dad) Allele alternate forms of genes produce different characteristics. Some traits are dominant mask effects of other genes example is the huntington"s disease. Recessive traits expressed only in the absence of another dominant gene. Can be passed on even if no phenotype expressed, example is blue eyes.
