Piebald Rats and Selection: An Experimental Test of the Effectiveness of Selection and of the Theory of Gametic Purity in Mendelian Crosses (Classic Reprint) - Softcover
Synopsis
A rigorous, long-running test of how selection and crossbreeding shape a trait in rats.
This study examines whether selection alone can shift a hooded coat pattern in rats, challenging the idea that gametes are always pure in Mendelian crosses. It covers years of careful experiments, large sample sizes, and careful data analysis to explore the genetics behind the trait.
The work frames a key question in heredity: can a population be steered toward a higher or lower expression of a trait without introducing cross-breeding? It documents the experimental setup, the series of selection lines, and how results were recorded and interpreted. The authors discuss patterns such as regression of offspring toward the population mean and what this means for the existence of stable, pure lines.- Learn how the plus and minus selection lines were run and how offspring grades were tracked across generations.
- See how the researchers tested the behavior of a supposed mutant and its influence on offspring in different crosses.
- Understand what the results suggest about dominance, heterozygotes, and the potential for homozygous mutants to alter mean traits over generations.
- Get a sense of the careful methodology, from grading schemes to how generations were grouped and analyzed.

Piebald Rats and Selection (Classic Reprint)
Print on DemandSeller: Forgotten Books, London, United Kingdom
Seller rating 4 out of 5 stars
Paperback. Condition: New. Print on Demand. This book dives into the complex genetic makeup of Piebald rats and the fascinating effects of selection on their distinct coat patterns. The author, a leading expert in the field, embarked on a six-year investigation to unravel the mysteries surrounding the genetic inheritance of these animals. Through meticulous experiments involving controlled breeding and observation, the book unveils the intricate relationship between genes and the visible characteristics of these rats. The author's findings challenge the long-held belief that genetic inheritance is immutable, demonstrating instead that careful selection can induce significant changes in the genetic makeup of a species. These findings have significant implications for our understanding of genetics and the potential for selective breeding in both animals and plants. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format.
