Document Summary

3. 5 what is the genetic basis of psychological science. Genome: the master blueprint for where everything goes. The genome provides the options, and the environment determines which option is taken. Chromosome: structures within the cell that are made up of dna, segments that are individual genes. Each genes has a specific instruction to make a distinct polypeptide (make up a protein) Proteins are the basic chemical that make up a cell and direct their activities. Environment determines which proteins are produced and when they are produced.

The number of genes might be less important than how those genes are expressed. Gregor mendel: selective breeding controlling which plants bred with who. Recessive gene only expressed when it is matches with a similar gene from the other parent. Determined at the moment of conception and never changes. Phenotype: observable physical characteristics and is always changing.
