Zygodactyl
Definition:
(n.) Alt. of Zygodactyle
Example Sentences:
(1) With fingers fused incompletely so called zygodactylous triradius and the main Z line may appear, instead of or alongside with them.
(2) Prevous findings by other authors with respect to: (1) zygodactylous tendency in the palms, (2) tendency for the ridge width to increase with the number of sex chromosomes, and (3) greater effect of an extra X chromosome in pattern size reduction but lesser influence on ridge width than an additional Y chromosome, were confirmed.
