Chapter 18: Quantitative Genetics I – Important Concepts Continuous Variation
نویسنده
چکیده
In the chapter on Mendel and Morgan, we saw how the transmission of genes from one generation to another follows a precise mathematical formula. The traits discussed in that chapter, however, were discrete traits—peas are either yellow or green, someone either has a disorder or does not have a disorder. But many behavioral traits are not like these clear-cut, have-it-or-don’t-have-it phenotypes. People vary from being quite shy to very outgoing. But is shyness a discrete trait or merely a descriptive adjective for one end of a continuous distribution? In this chapter, we will discuss the genetics of quantitative, continuously distributed phenotypes.

In this chapter, we will consider several of the major statistical concepts used in behavioral genetics and then provide an overview of the major methods used to estimate them. First, we explain in English the six important concepts in quantitative behavioral genetics: (1) heritability, (2) environmentability, (3) genetic correlation, (4) environmental correlation, (5) gene-environment interact...

Broadly speaking, there are two kinds of gene concepts. In this brief chapter I will offer a modest account of each. I seek to show that both are legitimate and that it is necessary to understand their interplay in order to understand the history of genetics and a number of current issues in genetics. I argue that the first kind of concept makes sense of the conceptual continuities in the histo...

As background for the rest of the lectures in this course, our goal is to introduce some basic concepts from Mendelian genetics (the rules of gene transmission), population genetics (the rules of how genes behave in population), and quantitative genetics (the rules of transmission of complex traits, those with both a genetic and environmental basis). We start with what (at first) may seem somew...
