The book "Problems of Genetics" by the famous British geneticist William Bateson is one of the first scientific works that highlight the fundamental problems of genetics. In the book, the author examines the issue of heredity and variation in living organisms, studies the laws of genetic inheritance and their influence on the development of species. Bateson offers new views on evolution and the genetic mechanisms of its implementation. This book became a classic source of knowledge in the field of genetics and a huge contribution to the development of biological sciences.
