Figure 3. Evidence of inbreeding in date palm genomes.
(a) Density distribution of the proportion of heterozygous genotypes in 50 kb windows for four date palm cultivars. Peaks in the distributions at low heterozygosity are apparent in the more inbred samples (b) An example run of homozygosity (ROH) in cv. Ajwa compared with cv. Mazafati on genome assembly scaffold S000023. Lines are loess fits to the proportion of heterozygous genotypes in non-overlapping 20 kb windows.
