Figure 2. Major effect alleles at major color pattern loci segregating in the H. himera×H. erato mapping families.

(A) Distinct geographic races of H. erato and the sister species H. himera used in the mapping crosses. (B) Homozygous phenotypes of the loci that control the distribution of black pigment (“melanin shutter genes”). (C) Homozygous phenotypes produced by the D locus. Allelic variation at this locus controls the distribution of red and yellow color patterns. See text for brief description of major color pattern loci.
