Document Summary
Chapters: 7, 9, 10, 11, 12, 13, 14, 15 and main points from labs. Note: *** = extra term found in powerpoint slides. Complete range of genes present in a species. Two species mate, offspring are a new species that can reproduce, but have reproductive isolation from parent species. Development of 2+ genetically differentiable species from single common ancestor (macro- Successive speciation within a single species line (micro-evolution) Adaptive radiation resulting in multiple different species (macro evolution) Chemical structures in cells that are passed on from parent to offspring (inherited) and control basic physiology, anatomy and behavior = contain information for building proteins which are functional units of life. Dna is packaged into paired, threadlike structures in cells. Differences in physiology, anatomy, behavior of species or individuals. Result of genotypic variation and strongly influenced by environmental conditions. Transfer of alleles or genes from one population to another.
