ANTA01H3 Chapter Notes - Chapter 3: Adaptive Radiation, Genetic Drift, Gene Flow
Document Summary
Chapter 3 of understanding humans: introduction to physical anthropology and archaeology. Topics: genetics and processes of evolution, sexual selection. Genetics: how traits are transmitted from one generation to the next . Gene structure and transmission of traits from parent to offspring. Basic structures of the cell relevant to this course = Prokaryotic cells; 3. 7 billion years old, single celled organism. Eukaryotic cells; 1. 2 billion years old, more complex, multiple structures/organelles. Proteins are made up of amino acids, sequences of certain amino acids will produce a multitude of possible proteins. Protein synthesis takes amino acids (sequenced by dna) and rna that reads the instructions" and assembles the amino acids. Explored the various way in which physical traits could be expressed in plant hybrids . Alleles, more than one variation/possible form of a gene. Recessive (not expressed, still present in gene) or dominant (expressed physically) allele/trait.
