An Introduction to a Biology 



a goose will lay golden eggs or not until it has begun 

 to lay. 



This article is intended merely as an introduction to the 

 subject. The most elementary treatise on it is " Breeding 

 and the MendeUan Discovery " (Cassell and Co.), by the 

 present writer. An excellent account of the whole subject 

 of Heredity is given in J. A. S. Watson's '' Heredity " (the 

 People's Books series). For fuller information on the sub- 

 ject of Mendelian Heredity the reader is referred to R. C. 

 Punnett's " Mendelism " (Macmillan and Co.) ; and for 

 an exhaustive treatment of the whole subject to Bateson's 

 classical work, " Mendel's Principles of Heredity " (Cam- 

 bridge University Press).
