  • a Approximate bounds on intervals were determined by the position of the first nonsignificant marker flanking the significant marker.

  • b Gene names are given in Lindsley and Zimm (1992). Candidate genes affect bristle number development or have bristle number mutant phenotypes, with the exception of the small heat shock proteins (Hsp22-Hsp-G3) and Superoxide dismutase (Sod), which are listed because they are sensitive to environmental conditions.

  • c References are to studies mapping bristle number QTLs in which the same interval was significant: (1) Breese and Mather 1957; (2) Gibson and Thoday 1962; (3) McBride and Robertson 1963; (4) Wolstenholme and Thoday 1963; (5) Thoday et al. 1964; (6) Spickett and Thoday 1966; (7) Davies 1971; (8) Frankham 1980; (9) Frankham and Nurthen 1981; (10) Shrimpton and Robertson 1988; (11) Mackay and Langley 1990; (12) Lai et al. 1994; (13) Long et al. 1995; (14) Mackay and Fry 1996; (15) Long et al. 1996; (16) M.
