(1) Both males and females have a form of polydactyly (the presence of extra fingers or toes) and congenital heart disease.(2) True polydactyly more commonly occurs on the feet and may be present with malformation syndromes.(3) However, polydactyly and limb-reduction defects occurred more frequently in regions that had the higher levels of contamination; differences were statistically significant for both types of malformations.(4) The incidence of polydactyly (supernumerary digits of hands or feet) is the same in both sexes, with simultaneous polydactyly of the hands and feet present in about one third of cases.(5) polydactyly of both hands was noted at birth(6) Since postaxial polydactyly is an autosomal dominant trait, we may hypothesize that the two people who had served as models for Raphael were relatives, probably father and son.(7) For instance the limitation of digit number to a maximum of five among recent amniotes cannot be explained by a developmental constraint per se since polydactyl limbs appear quite frequently.(8) Cats with this mutation are known as polydactyls (from the Latin for ‘many digits’), or as Hemingway cats.(9) He's a tremendously cute, long-haired, orange polydactyl (extra toes) male who has a bit of a Maine Coon Cat look to him.(10) About half the cats are polydactyl , they and others are descendants of a six-toed cat given to Hemingway by a ship's captain.
