The results are presented of a study of ulnar loops in complete or partial symmetrical formulae, in all possible combinations, in a sample of 200 families taken at random in the population of Montevideo.

Some partial formulae not only appear in a significantly higher proportion when both parents have them, and in a smaller amount when they lack them, but also seem to be inherited in a higher degree than the theoretical expectancy of the combined chances of the patterns they are made up of.

The authors' conclusions is that there seems to be a basic influence of factors determining the inheritance of independent patterns, plus a second one, resulting from the meeting of some patterns to give a more remarkable genetic effect for the inheritance of partial formulae.
