Note 10 — Chapter II
Reading edition
Davenport inclined at first to regard rumplessness as a recessive, but in his latest publication on the subject he definitely concludes that it is an imperfect dominant. This conclusion accords well with evidence quoted by Darwin (An. and Plts., II, ed. 2, p. 4) that rumpless fowls may throw tailed offspring. (Amer. Nat., 1910, XLIV, p. 134.)
