Handedness of regenerated limbs in C. gracilis Contralateral autotransplantation of claw tissues into eye sockets regenerated six claws with recognizable hand- edness. Among them, two claws had host-site handedness (Fig. 2A), three claws had donor-tissue handedness, and one claw had a mixture of host and donor handedness (Fig. 2B). The two claws with host-site handedness re- sulted from contralateral autotransplantation of a combi- nation of distal and proximal claw tissues (dactyl + pollex + ischium; Fig. 2A), or proximal claw tissues (ischium + menus/carpus joint). The claw with a mixture of host and donor handedness resulted from autotransplantation of a combination of distal and proximal tissues (dactyl + pollex + ischium; Fig. 2B). It had donor handedness at its distal parts and host handedness at the proximal parts of the claw. The claw digits regenerated first, and the proximal segments regenerated during subsequent molts. Ipsilateral autotransplantation of claw tissues regenerated three claws with recognizable handedness. These three claws retained the donor (same as the host-site) handed- ness (Fig. 2C). Contralateral autotransplantation of the fourth walking leg tissues into eye sockets regenerated one walking leg with recognizable, donor-tissue handed- ness (Fig. 21). Autotransplantat
