Studies of phenotypic selection document directional selection in many natural populations. What factors reduce total directional selection and the cumulative evolutionary responses to …
How strong is phenotypic selection on quantitative traits in the wild? We reviewed the literature from 1984 through 1997 for studies that estimated the strength of linear and …
Directional selection is a major force driving adaptation and evolutionary change. However, the distribution, strength, and tempo of phenotypic selection acting on quantitative traits in …
Comparative studies of the genetic architecture of different types of traits were initially prompted by the expectation that traits under strong directional selection (fitness traits) …
950 NOTES AND COMMENTS evolutionary dead ends with little capacity for change. These latter authors argue, however, that random genetic drift can disrupt these coadapted gene …

Conditions for polymorphism at pleiotropic loci with antagonistic effects on fitness components are investigated, under the assumptions of additivity and multiplicativity of …

Phenotypic variation of traits studied in wild populations is the result of many different genes acting in concert, often in combination with environmental variation introduced during …
Compared to those of their parents, are the traits of first-generation (F1) hybrids typically intermediate, biased toward one parent, or mismatched for alternative parental phenotypes …
A genetic model with either 64 or 1,600 unlinked biallelic loci and complete dominance was used to study prediction of additive and dominance effects in selected or unselected …
