A scientific guide to how heredity and genetics are intertwined. Written by the once Professor of biology at McGill University, W. Lochhead. Written with style and separated into easy to handle sections. Many of the earliest books, particularly those dating back to the 1900s and before, are now extremely scarce and increasingly expensive. We are republishing these classic works in affordable, high quality, modern editions, using the original text and artwork.

The journal discusses articles on gene action, regulation, and transmission in both plant and animal species, including the genetic aspects of botany, cytogenetics and evolution, zoology, and molecular and developmental biology.
