Evolutionary psychology: survival of the fittest behavior. David buss-evolution affects how we make decisions/how aggressive we are/fears/mating patterns. Dna-complex molecules that have a double helix shape and contains genetic information. Human genome project-identifies map of human genome, full of the complete set of developmental information for creating proteins that initiate the making of a human organism; humans have 30,000 genes. Linkage analysis-goal is to discover the location of one or more genes in relation to a marker gene to find disease genes. Next-generation sequencing-vast increase in genetic data generated at a much reduced cost in a shorter period of time. Meiosis-cell division that forms eggs and sperm. Fertilization-when egg and sperm fuse to create a single cell. Zygote-fusion of egg and sperm to a single cell. Phenotype-a person"s observable characteristics, including physical traits. Dominant-recessive genes-when some genes trump others depending on its dominant characteristics. Sex-linked genes-different implications depending on x or y-linked genes.
