Fig. 5From: The wild grape genome sequence provides insights into the transition from dioecy to hermaphroditism during grape domesticationEvolutionary genomic scenario of the formation of the X and Y haplotypes and reversal to hermaphroditism. a Reconstructed gene content and order in the hermaphroditic ancestor (before the evolution of dioecy). b Formation of the X and Y haplotype in the dioecious ancestor of all Vitis species. c Formation of the Yh haplotypes through a modification of the expression of the genes involved in female sterility (standard Yh) and/or by a rare recombination event at the APTR3 gene (Yh′)Back to article page
