Synopsis
Excerpt from A Study of Selections for the Variation and Inheritance of the Size, Shape and Color of Hens' Eggs: A Thesis Presented to the Faculty of the Graduate School of Cornell University for the Degree of Doctor of Philosophy
The study of the external characters of eggs seems to date from a com paratively recent period, and even at the present time the published data with respect to these characters are very meager.
Tradition tells us (in Horace, Lib. II, st. 4) that the eggs of pullets are longer than those of hens, and that pullets' eggs produce a larger proportion of male chicks than do hens' eggs. This tradition has been developed until many persons believe that long eggs produce cockerels and round eggs produce pullets when incubated.

A Study of Selections for the Variation and Inheritance of the Size
Print on DemandSeller: Forgotten Books, London, United Kingdom
Seller rating 5 out of 5 stars
Paperback. Condition: New. Print on Demand. This book offers an in-depth study of the inheritance of egg characteristics in poultry through the analysis of size, shape, and color variations. The study conducted by the author over several years involved selective breeding of hens and the detailed examination of their egg production. The author begins with a review of existing literature on the subject, highlighting the limited research and the inconsistent findings regarding the inheritance of egg characteristics. Through meticulous observation and data analysis, the author provides compelling evidence for the heritability of these traits, specifically demonstrating the influence of both maternal and paternal lineages on the phenotype of the offspring's eggs. The book also explores the relationship between egg characteristics and other factors such as the age of the hen, the time of year, and the hen's overall health. The author's findings shed light on the complex interplay between genetics and environmental influences on egg production. This book is a valuable resource for poultry scientists, geneticists, and anyone interested in the inheritance of quantitative traits. It contributes significantly to the understanding of the genetic basis of egg characteristics and provides practical insights for selective breeding programs aimed at improving poultry production. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item. Seller Inventory # 9781333423056_0
