Document Summary
Chapter 2: independent questions: biological and evolutionary theories. Summarize the two introductory paragraphs of this section: genetics, genotypes, phenotypes, and patterns of inheritance, define the following terms related to genetics: (a) chromosomes, (b) dna, (c) genes, (d) genome. Chromosomes finely coiled dna molecules (23 pairs) Genes segments of dna that influence a particular feature or developmental pattern. Genome all the dna an organism possesses: dominant and recessive genes - optional reading, polygenic and multifactorial inheritance, heredity is the passing of traits to offspring (from parents or ancestors). There are many different patterns or rules of heredity/inheritance. Some inherited traits are referred to as mendelian traits (that is, traits that are under the direct control of a single gene). Predicting the expression of traits determined by a single gene (mendelian traits/monogenic inheritance) is relatively straightforward. A phenotype like height that is influenced both by genetics and environment: epigenetics epi-upon gene function but not necessarily gene structure.
