Genetic characterization of doubled haploid population. (A) Genotype of a typical doubled haploid. Each point represents a single SNP with either an NFA-8 allele (blue) or Sq-8 allele (red). Chromosomes 1, 3, and 5 are recombinant products of a single crossover event in the parental meiosis (Sq-8 × NFA-8 F₁ hybrid). Chromosome 4 is a double recombinant and chromosome 2 is a nonrecombinant NFA-8 parental chromosome. (B) Comparisons of marker locations between the physical (black) and genetic (purple) maps. Only the 1,043 markers used to build the genetic map are shown. (C) Sliding window (250 kb) average of genome-wide NFA-8 allele frequency for each chromosome (1-kb step size).
