Reduced nucleotide diversity in the X region of papaya. Nucleotide diversity (π) is plotted along chromosome 1 in sliding windows of 100 kb with step size of 25 kb. Nucleotide diversity in gynodioecious papaya from domesticated samples (including X-linked regions of both hermaphrodites and females) is plotted in red and for wild dioecious populations (including males and females) in blue
