Hox Genes Phylogeny.png The figure above shows the number of Hox gene clusters in different groups of animals. What do you notice about the sequence of Hox genes in each cluster? Where do you see a reversal? Does this make sense to you for the group that it is in? Where do you see the loss of Hox genes? Where do you see duplication of Hox genes
