Document Summary
Chapter 2: independent questions: biological and evolutionary theories. 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. However, unlike monogenic inheritance, polygenetic and multifactorial inheritances are complex. (a) what does polygenetic (comes from many gene) inheritance mean? (b) what does multifactorial (many genes and the environment) inheritance mean: epigenetics (affects genes function not structure) Some of the traits we inherit cannot be explained by our genes/genome. Epigenetics is a recent theory that suggests heritability can be operating above the genetic level: define the following terms: (a) epigenome, (b) gene expression, (c) gene silencing. However, because the correlations found are less than +1. 00, environmental factors must also contribute to intelligence and attitudes.
