Document Summary
Chapter 2: independent questions: biological and evolutionary theories. Summarize the two introductory paragraphs of this section. Both genetics and epigenetic factors interact with environmental variables to shape our level of health and well-being across the lifespan. Are made up of about 2metres of finely coiled dna molecules (b) dna: a chemical material that makes up a chromosome (c) genes: complex chemical units of a chromosome that control or influence inherited traits. Each chromosome is divided into these segments. 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 pattern of inheritance in which many genes influence a trait. Children get three genes for skin colours from their parents. Dark skin is dominant over light skin, but skin colour also blend together.
