A Review of Literature on Chromosome Studies of the Fowl

LITERATURE REVIEW AN INTENSIVE chronological review of the literature on chromosome studies of the domestic fowl (Loyez, 1906; Sonnenbrodt, 1908; Guyer, 1909; Lecaillon, 1910; Boring and Pearl, 1914; Guyer, 1916; Cutler, 1916; Swift, 1916; Boring (on Stevens), 1923; Crew, 1923; Shiwago, 1924; Hance, 1924, 1925, 1926a, b, c, Akkeringa, 1927; Goldsmith, 1928; Kemp, 1930; Suzuki, 1930; Saguchi, 1931; White, 1932; Popoff, 1933; Sokolow and Trofimow, 1933; Unger, 1936; Sokolow, Tiniakow and Trofimow, 1936; Miller, 1938; Scaccini, 1944; and Yamashina, 1944), which is summarized in Table 1, shows widespread investigation but almost universal disagreement. No one has yet clearly demonstrated the characteristic number of chromosomes of domestic or wild types of fowl, nor the type of sex inheritance, nor the sex chromosome. Through the period between Loyez (1906) and Yamashina (1944), the diploid number of chromosomes has increased from 6 pairs to 39 pairs (plus or minus 1). The XO-type of . . .
