The SNP and indel distribution on chromosomes of the two parents. A Gene density in the genome (gene numbers per 50 kb, max = 16); B SNPs per 50 kb on Yugu18 (max = 278); C indels per 50 kb on Yugu18 (max = 24); D SNPs per 50 kb on Jigu19 (max = 399); E indels per 50 kb on Jigu19 (max = 28); F effective genetic variants between the two parents (max = 154); and G genome distributions of the final genetic variations used for bin map construction. Red lines indicate relatively higher variation densities
