Mutation models and quantitative genetic variation.
Analyses of evolution and maintenance of quantitative genetic variation depend on the mutation models assumed. Currently two polygenic mutation models have been used in theoretical analyses. One is the random walk mutation model and the other is the house-of-cards mutation model. Although in the short term the two models give similar results for the evolution of neutral genetic variation within...
متن کاملQuantitative Genetics and Quantitative Traits
Introduction In the chapter on Mendel and Morgan, we saw how the transmission of genes from one generation to another follows 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 the disorder. But many behavioral traits are not like these clear-cut, have-it-or-don’t-have-...

متن کاملQuantitative Genetics
Genetic analysis of quantitative traits is applied in a wide variety of substantive research areas. Many human characteristics exhibit continuous variation, such as height, weight, intelligence or personality, but the application of quantitative genetics is not limited to traits thought to be continuous. For example, eye color may be assessed in a qualitative fashion – blue versus brown versus ...
متن کاملQuantitative Genetics
Essentially all characters show some phenotypic variation, either between individuals within a population and/or between populations. Such variation is probably due to both genetic and environmental differences. Sorting out the nature of these genetic differences, the relative importance of genetic versus environmental factors, and how this phenotypic variation translates into evolutionary chan...
