Quantitative Genetics of Autogamous F2

Quantitative 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 ...

Quantitative 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...

Quantitative 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-...
