Synopsis

This book is a comprehensive analysis of the effects of selection on bristle number variation in Dichaet, a mutated strain of the fruit fly. The study is part of a larger series of experiments aimed at understanding the relative influence of genetic inheritance and environmental factors on observable characteristics in the fruit fly. The author explores whether the variation is due to modification of the mutant gene itself or to the influence of multiple factors, as suggested by the multiple-factor view of inheritance. The primary conclusion of the book is that selection operates by isolating existing genetic variations rather than creating new variations, supporting the multiple-factor view of variation and inheritance. This book provides compelling evidence for the stability of genes, challenging the hypothesis that genes are easily contaminated in heterozygotes and mutate frequently.
