Fig. 3: Crossovers occur every meiosis without loss of heterozygosity.

Karyoplot depicting crossovers (tick marks) inferred between each pair of phased genomes from linked-read sequencing data and all pairwise comparisons (All pairwise) between the different families of unknown pedigree. The numbers of sites at which crossovers are detectable per 200 kb window are shown as a grey histogram (Detectable sites). For each pair, we show to the right of the karyoplot the proportion of the genome phased in both samples (that is, the proportion of the genome for which crossovers are detectable), the total number of crossovers detected, the number of losses of heterozygosity expected and the number of losses of heterozygosity observed. Assuming Mendelian segregation, two-thirds of inherited crossovers should be associated with loss of heterozygosity but, surprisingly, only one of the observed crossovers was.
