Linkage map, extent of deviation from Mendelian segregation, and genotype frequencies in LG3M. (A) Schematic chart of LG3M. (B) Degree of deviation from the expected 1:2:1 segregation along LG3M. The x-axis represents the position in LG3M; y-axis represents χ²-test P-values for distorted segregation. Each white dot represents female progeny; the black dots represent male progeny. The y-coordinate of female progeny is based on the homologous marker of the male linkage map. The dotted line represents α = 0.001. (C–D) Each line represents the genotype frequency of loci positioned on LG3M. AA denotes a homozygote derived from the grandmother; BB denotes a homozygote derived from the grandfather; AB denotes a heterozygote.
