Paperback. Condition: New. Print on Demand. This book explores the phenomenon of mutations in the species Aspergillus niger, a very common mold. The author conducted a series of controlled experiments to determine the frequency and cause of mutations in this species and found that they can be triggered by extreme conditions such as high temperatures or the presence of toxic substances. The book also investigates the stability of mutations through successive generations and discusses their implications for our understanding of heredity and evolution. Moreover, the author presents several novel ideas to explain the nature and causes of mutations, challenging the currently accepted theories. Overall, the book offers a new perspective on the causes of genetic mutations by systematically testing theories on a specific organism. 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.

This book examines the surprising phenomenon of spontaneous, seemingly causeless variation in plants, an area of genetics to which the author has made several groundbreaking contributions. A fundamental concept in genetics is that every characteristic of a living being is controlled by a gene or genes which cause its expression in the offspring of the parents. A mutation occurs when these genes change spontaneously, causing dramatic departures from expected genetic norms. This volume investigates the idea that not all variation is due to mutations, and in certain cases genetically uniform populations of plants may give rise to progeny which deviate profoundly from their parents, as if a segment of the organismâs hereditary material had been lost. The author's focus on this little-understood phenomenon is significant because it offers a glimpse into the processes by which new species may come about, and the potential for further agricultural breakthroughs.

Paperback. Condition: New. Print on Demand. This book marries Mendel's theories of heredity with the study of quantitative characters in tobacco. The author, a leading expert in the field of tobacco breeding, explains his methods for the inheritance of certain quantitative characters in tobacco: namely the number of leaves, length of leaves, width of leaves, and length of internodes. The author provides meticulously detailed descriptions of his methods, along with an accounting of his experimental results. Through selective breeding, the author was able to show that the quantitative characters he was studying were indeed heritable, meaning they could be passed on from one generation to the next. The study of quantitative characters in this book is an important step forward in the field of genetics, as these characters are often the most important in terms of agricultural production.

Paperback. Condition: New. Print on Demand. This book provides intriguing insights into the evolution of echinoids, commonly known as sea urchins, delving into their fossil record to reveal profound changes that occurred during the Paleozoic and Mesozoic eras. The author analyzes the morphology of fossil echinoid coronas, the hard outer shells that provide vital clues to their biology and lifestyle. Through meticulous examination, the author unravels the complex relationships between different echinoid groups and explores how their characteristics evolved over time. This meticulous study contributes significantly to our understanding of echinoid systematics and sheds light on the evolutionary forces that shaped these marine invertebrates throughout geological history.

Paperback. Condition: New. Print on Demand. This book explores the inheritance of traits in dogs using experiments in crossbreeding and other scientific methods, leading to a greater understanding of genetics in dogs and contributing to the broader field of heredity. The author begins with a discussion of the existing body of knowledge on the subject and then presents the results of their own experiments, which provide evidence for the alternative inheritance of certain traits, such as coat color and length. They also explore the potential role of mutations in the development of new breeds, such as the dachshund's distinctive short legs. Ultimately, this book provides valuable insights into the genetic basis of canine traits and the inheritance of characteristics in animals.
