Document Summary
Bio1011 lecture 9 patterns of inheritance 1. "the study of inherited variation to solve biological problems, either natural or induced variations. " Traits/ characteristics: genes/ dna/ chromosomes, genotype/ phenotypes. Transmission genetics how traits are passed from parents to offspring. Molecular genetics how the hereditary material controls the expression of genes and thus traits. Evolutionary and population genetics genetic variation and its role in evolution. Ancient cultures recognised that offspring resembled parents. Selective breeding in agriculture led to various theories: pangenesis. Traits and skills that could be passed down to offspring. Mother could play the piano, offspring should be able to play the piano: homunculus. There was already males inside the sperm, but females weren"t. Blending theory: where traits are blending into offspring from parents. Mendel discovered the laws of inheritance in the 1860s. Why did he succeed in his theory: used good model organisms, simple traits, organism either one or the other version of trait (appearance = phenotype).
