Polydactyly in Arctic foxes (Vulpes lagopus)
Seven Arctic fox puppies were found to have an extra claw (resembling a canine dewclaw) on their thoracic limb. These individuals came from 2 litters born of 2 different females. The "dewclaw" comprised a claw loosely connected with the limb by soft tissue, and it had the third phalanx (PI...

Summary: | Seven Arctic fox puppies were found to have an extra claw (resembling a canine dewclaw) on their thoracic limb. These individuals came from 2 litters born of 2 different females. The "dewclaw" comprised a claw loosely connected with the limb by soft tissue, and it had the third phalanx (PIII) and a vestigial phalanx. Our results show that the presence of an extra claw on one or both hands in some Arctic fox puppies may, but does not have to, be a dominant trait. The differences between the 2 analyzed litters support the hypothesis that the mode of inheritance of the investigated trait in Arctic foxes could be more complex. |
