The Inheritance of Accessory Triradii on Palmar Interdigital Areas II and IV

Abstract

SUMMARYData obtained from 53 Panjabi Khatris families were tested for mode of inheritance of patterns on palmar interdigital area II. Gene frequencies were obtained from 1,000 unselected Panjabi Khatris.Analysis of the data indicate that a single dominant gene, with approximately 88% penetrance, is responsible for D patterns in both the second and fourth interdigital areas of the palm.
