Why I'm Like Dad
ABOUT THE B O O K Why do cats give birth to kittens, lions to lion-cubs, and rabbits to baby rabbits? Why do human children, too, not only outwardly look like their parents, but also resemble them in character and disposition? Why are twins as like as two peas or quite different? Why are some babies born monsters? Can man remake animalsand plants to order? Questions like those are the field of this book. It describes the quests that led to major discoveries in genetics, and the obstacles encountered by researches, and tells about the scientists who study heredity, and how to change it. The author, a prominent biologist himself, takes the reader to research laboratories, farm fields, and hospitals, opening up before him the wholebroad field of modern genetics. Why I'm Like Dad received the award of the USSR Society for the Dissemination of Scientific Knowledge (Znaniye) for the best popular science writing in 1967.

Professor Carl von Naegeliof Munich University was famous as a stickler for precision and punctuality. And was proud of it. That may be why, as professor of botany, he had chosen hawkweeds (Hieracium) as the subject of his research, plants with crowns of yellow flowers resembling dandelions or sow-thistle. For work w i t h them requires the utmost accuracy. The professor was exact in everything and always answered letterspunctually. B u t one letter he had not answered for nearly two months, and that bothered h i m . But w h a t to say in reply? The letter had not come from a scientist, that was obvious from the subscription: 'I remain, Your Excellency's respectful and humble servant, Gregor Mendel, Canon of the Monastery and teacher a t the Realschule.' B u t the date was 31 December 1866, and here it was...
