About this book
Mendelism is a book by Reginald Crundall Punnett. The title page marks the book as a third edition, entirely rewritten and much enlarged. The text says the male sexual cells are always of microscopic size and are produced in the generative gland or testis in exceedingly large numbers.
The text says that, for fertility (F) and the dark axil (D), the experimental numbers accord with the view that the gametic series is here 15 FD : 1 Fd : 1 fD : 15 fd. The text says the coupling between blue and long pollen is generally on the 7 : 1 : 1 : 7 basis, but in some cases it may be on the 15 : 1 : 1 : 15 basis. The text asks, of a distinguished son who follows in the footsteps of a distinguished father, whether this is due to the inheritance of a particular mental aptitude or is an instance of general mental ability displayed in a field rendered attractive by early association.
