To determine which organisms on the cladogram have claws or nails, we need to know the specific branching points that indicate the presence of claws/nails. Generally, organisms in the clade of reptiles, birds, and mammals tend to have claws or nails.
Based on typical classifications in cladograms, mammals (including the mouse and chimp) usually have nails (or claws), while reptiles might have claws. If there are specific organisms listed in your cladogram, you would typically mark all mammals and reptiles as having claws or nails.
Unfortunately, I cannot view the actual cladogram you are referencing. If you can provide a description of the different organisms presented in the cladogram or the points at which claws/nails are marked, I can help you identify which ones have claws or nails.
