Stabilising selection decreases genetic variation within a population, natural selection that favours less common, more extreme phenotypes. characteristics that exhibit continuous variation are usually determined by many genes, so they're polygenic, directional, stabilising, disruptive / dispersive, natural selection that favours intermediate phenotypes, and extreme phenotypes are selected against. erosion of a coast line), changes that have no rhythm & no constant direction (e.g. how might 1 allele inhibit the expression of another? genetic bottleneck effect and founder effect, there's a sharp decrease in the size of a population due to an environmental catastrophe (e.g. Chapter 13 (PDF) Chapter 14 (PDF) Chapter 15 (PDF) Chapter 16 (PDF) Chapter 17 (PDF) ...

Learn vocabulary, terms, and more with flashcards, games, and other study tools. GM E. coli makes human insulin to treat all diabetics & human growth hormone to treat children with pituitary dwarfism, GM microorganisms must be carefully contained - if they're released into the wild they could transfer marker genes for antibiotic resistance to other bacteria, GM soya beans resistant to a certain herbicide have been produced, so weeds competing with the soya plants would be killed by the herbicide, the gene for herbicide resistance could pass into the weeds, creating 'super weeds', - GM viruses, genetically modified to have no virulence, can be used to make vaccines, in gene therapy, genetic modification increases the risk of cancer, GM mice are used for medical research (e.g. Homeostasis excretion as an example of homeostasis neuronal communication hormonal communication plant and animal photosynthesis...
