About this book

Approximately 99.9% of vertebrate species reproduce sexually. The exceptional 0.1% reproduce via asexual or clonal means, which vary wildly and are fascinating in their own right. In Clonality: The Genetics, Ecology, and Evolution of Sexual Abstinence in Vertebrate Animals, John C. Avise describes the genetics, ecology, natural history, and evolution of the world's approximately 100 species of vertebrate animal that routinely display one form or another of clonal or quasi-clonal reproduction.

By considering the many facets of sexual abstinence and clonal reproduction in vertebrate animals, Avise sheds new light on the biological meaning and ramifications of standard sexuality.

"The concepts in Clonality are vividly and entertainingly conveyed. [A] highly entertaining and thought-provoking book from a master of the field of evolutionary genetics."
- Trends in Ecology and Evolution
