What reading level is Heredity in Relation to Evolution And Animal Breeding book?
To quickly assess the difficulty of the text, read a short excerpt:
And when pigeons are crossed in captivity they frequently revert to the plumage condition of the wild rock pigeon, Columba livia. In plants, too, Darwin recognized that crossing is a fre- quent cause of reversion. The explanation 62 DOMINANCE which he gave was the best that the knowl- edge of his time afforded, but it leaves much to be desired. This lack, however, has been completely supplied by the Mendelian princi- ples. An illustration or two may now be cited.
When pure-bred black guinea-pig...s are mated with red ones, only black offspring are as a rule obtained. The hairs of the offspring do indeed contain some red pigment, but the black pigment is so much darker that it largely obscures the red. In other words, black be- haves as an ordinary Mendelian dominant. In the next generation black and red segregate in ordinary Mendelian fashion, and the young produced are in the usual proportions, three black to one red, or 1 : 1 in back-crosses of the heterozygous black with red. All black races behave alike in crosses with the same red in- dividual, but among red animals individual differences exist.
