A conceptual model to explain phenotypic complexity using reaction norms at multiple levels with varied environmental inputs. (A) Reaction norms at the single-locus level to temperature changes. Two homozygous genotype classes are represented by two alleles for the gene Hd1. (B) Reaction norms at the multilocus haplotype level to temperature changes. The 24 = 16 haplotype (homozygous genotype) classes are shown for four genes (Hd1, Hd2, Hd5, and Hd6). (C) Reaction norms at the genome level observed as individual organisms to temperature changes.
