Clade-based missing data. A true species tree on seven species (labeled A-G) and five true gene sequence alignments (colored red, yellow, green, blue, and purple) are shown in this schematic. The red, green, and blue genes have no missing data. The yellow and purple genes have clade-based missing data, created by selecting a clade in the true species tree at random and then deleting taxa outside of the clade from the true gene tree (not shown) and the true gene sequence alignment. For the yellow gene, the clade containing A, B, and C is selected from the true species tree, and hence, species D, E, F, and G are deleted from the yellow gene. Similarly, for the purple gene, the clade containing D, E, F, and G is selected from the true species tree, and hence, species A, B, and C are deleted from the purple gene
