Part 2: Monohybrid Cross. Randomly (without looking) take two beads out of Beaker 1. This is the genotype of Individual #1. Record the genotype in Table 1. Do not put these beads back into the beaker.
The Norwegian Johan Vaaler is usually called the inventor of the paper clip. Norway had no patent office, so he filed an American patent for a set of square and triangular clips. That was in 1901. And maybe it was the first paper clip patent.
The information on this page is based on our review of patents, early trade publications, artifacts, and other primary sources. As a result, unlike much of the information on the history of the paper clip that is available on the internet, the information presented here is accurate. The Early Office Museum is grateful to Kenneth R. Berry for sharing his patent and trademark research on paper clips.
