Document Summary
Overview of the course: ecological and evolutionary genetics. Genetics ensures transmission across generations (a. k. a. evolution: use our knowledge of genetic principles to understand evolutionary and ecological phenomena, use our knowledge of behaviour and ecology to deduce the mechanisms that produce patterns in genetic data. Birds are heterogametic with w and z. Males have all z, females have w and z: autosomes 1 copy from each parent. There are high recombination areas where lots of crossing over happens during formation of gametes. There are low recombination areas near the centromere/telomeres with reduced recombination: mitochondrial dna in particular organism is inherited maternally. Sperm + egg fuse, but all of the cytoplasm come from the mother. Everything else is inherited from both sexes. How can we use these genome data: we can use regions of the genome that are inherited biparentally to infer the contributions of both parents. Y chromosomes track paternal lineages: combined application. Use genetic markers to understand the evolutionary process.
