This book explores how a barred color in ostrich feathers is a genetic trait passed down from their parents, rather than a heterozygous condition resulting from the mixing of black and white feathers. The author begins with historical accounts of barred ostrich feather observations and unsuccessful attempts to breed this trait. The author then presents the results of their own experiments, which led to the discovery of a factor for barring that, when inherited from both parents, results in barred feathers. This discovery challenged the prevailing view that barring was a mosaic of black and white feathers, as it appeared in the first generation of offspring from black and white ostrich crosses. The author concludes that barring is a unit-character inherited separately from black and white pigmentation, providing new insights into the nature of inheritance and the complexity of genetic traits in ostriches. 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.
