The definitions of these terms seem to overlap. Could we make them more distinct? If a mouse is missing 1 or two digits, would I annotate to both?
adactyly [MP:0000561] Definition: missing one or more digits, or all digits
oligodactyly [MP:0000565] Definition: congenital condition in which some digits or parts of digits are missing
Also consider position of:
monodactyly [MP:0003800] Definition: having only one toe or digit on each extremity
From the definitions, it would appear that monodactyly and oligodactyly could be children of adactyly
