Fig. 3From: Genomic heterozygosity and hybrid breakdown in cotton (Gossypium): different traits, different effectsThe constructed specifications for all markers and individuals in (3E) F2 (a) and (E3) F2 (b) and the frequency distributions of MHIs in (3E) F2 (c) and (E3) F2 (d). Each rectangle denotes an individual’s genotype at a given locus. Colours are arranged from darker green, indicating E22 homozygotes, to green, indicating heterozygote genotypes between E22 and 3–79, to light green, indicating 3–79 homozygotes. White blocks indicate missing dataBack to article page
