Fig. 1From: High-density genetic map construction and gene mapping of pericarp color in wax gourd using specific-locus amplified fragment (SLAF) sequencingNumber of markers and average sequencing depths of F2 population. The x-axes in both a and b indicate the F2 individuals. The y-axe in a indicates marker coverage, and the y-axe in b indicates the number of markers developed for each F2 plantBack to article page
