Unformatted text preview: Gregor Mendel, Austrian botanist and plant experimenter, was the first to lay the mathematical foundation of the science of genetics (Walter 123). Scientists have accepted Gregor Mendel’s laws of segregation and assortment since the three men by the names of de Vries, Tschermak, and Correns (Walter 123). However, Mendel wasn’t alive to know that. In the law of segregation, one of the four main concepts is when the two alleles of a pair are different, one is dominant and the other is recessive. When there is a heterozygous gene (for example, Pp), the dominant allele will mask the recessive trait. Even though Mendel found the law of segregation, he only tested pea plants and no other plants or tested animals. This can be a problem because maybe his law of segregation is only an exception to only pea plants, and not on other plants. In this plant variation experiment, can we replicate Mendel’s ideas by using mustard plants instead of his pea plants? This is so important because this may explain why plants have many different variations in traits. If Mendel’s law of segregation is true, then the mustard plant’s recessive trait should become visible in the F 2 Generation. To begin the experiment, the students took a small Styrofoam with four segregated areas. Afterwards, the students poked one hole in each quad and inserted a small paper into the hole. Then the students poured soil into each of the quads evenly and inserted the true-breeding seeds and the resulting seed into the quads. Afterwards, the plants grew for approximately two weeks in room temperature with a fair amount of light above them. After the two weeks have expired, the plants were observed and recorded of above them....
