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 list goes on and on: the âRinklip,â the âMogul,â the âDennison,â the âEzeon.â. Despite this period of wild experimentation, the narrow doubleloop form of the Gem has remained the most enduring paper clip design. The first time a recognizable Gem-type clip appears in patent literature is in 1899.
