Selection signatures of heterozygosity in cassava. a–c Comparison of genomic diversity between heterozygous and homozygous regions using the values of π and Tajima’s D in 374 cultivars as well as FST value between 14 wild progenitors and 14 randomly selected cultivars. The significance of difference was derived with two-tailed t-test (*P < 0.05, **P < 0.01). d Selection signals for decrease in heterozygosity and nucleotide diversity from wild cassava progenitors to cultivars. The upper (1.27) and lower (1.86) horizontal blue lines indicate values above the 99% thresholds for selection sweeps in heterozygosity and nucleotide diversity, respectively. Red arrows indicate the positions of growth- and development-associated genes that are differentially expressed in storage roots between wild progenitors and cultivars within selective sweep regions with both decreases in heterozygosity and nucleotide diversity. Annotation of these genes is shown in Additional file 19: Table S19
