Introduction In this experiment (polygenic traits), fingerprint patterns will be examined. Using the fingerprint total ridge count (TRC) from the population of male and female students in the biology class you will explore how the traits of TRC illustrate the polygenic inheritance model. The polygenic inheritance model describes the nature of fingerprint ridge patterns. Fingerprint ridge patterns result from environmental influences on the expression of a number of interacting genes. At least seven genes are thought to be involved in finger ridge formation (Penrose, 1969). There are three main types of fingerprint patterns: arches, loops (ulnar/radial), and whorls. It is founded that the average TRC of all ten fingers for males is 145, and for females is 126. Looking at the general population, the fingerprint ridge patterns tend to be: arch, 5.0%; radial loop 5.4%; ulnar loop, 63.5%; and whorl, 26.1%.
