Genetics: used to describe how the characteristics like height are passed along to offspring through inheritance and the process of turning genes on and off . Gene expression: whether a particular gene is turned on or off o. Environmental factors can affect this and possibly influence how a gene, once turned on, influences our thoughts, feelings, and behavior. Genetics predispositions influence environment and what environment people select for themselves (genes and experience influence development of brain. Genome: master blueprint that provides detailed instructions for everything. It provides options (part of liver or brain) and environment determines option taken o. Genome project: mapped entire sequence of dna by identifying order of molecules that makes up each of 1000s of genes on 23 chromosomes. 30,000 (lower and close to other animals) meaning that the number of genes are less important than how genes are expressed and regulated. Zygote: resulting cell from when 1 egg and 1 sperm combine.
