Clonality (eBook, ePUB)

The Genetics, Ecology, and Evolution of Sexual Abstinence in Vertebrate Animals

• Format: ePub

Produktbeschreibung

99.9% of vertebrate species reproduce sexually. This book describes the other 0.1%-the clonal reproducers. Asexual animals are inherently fascinating and also uniquely instructive about alternative reproductive modes. The author guides readers into the astonishing realm of sexual abstinence, from levels of DNA molecules and cells to whole animals and populations.
