Mendel's Pea Experiment

Gregor Mendel was a monk from Central Europe, he gave us the modern understanding of how genetics work. One of Mendel's famous experiments is one that he did with peas. Mendel took one green pea plant and crossed it with one yellow pea plant, his hypothesis was that the resulting offspring would be a yellow-green pea plant. Yet the result of his experiment was that all the offspring of the 2 pea plants were yellow! Thinking that he had made a mistake in the experiment, Mendel repeated this experiment many time, but he got the same result every time. Mendel then bred the first offspring generation (f1) and found that the second offspring generation (f2) had a ration of 3:1, which meant that out of 4 one pea was green while the rest were yellow. Looking at the experiment Mendel concluded from the f1 generation that the yellow gene was dominant and from the f2 generation that the green gene was recessive. This was not just relative to colour but to other traits as well. 

     In class we did a similar experiment where instead of growing our own plants, which would take a while, we took a bucket with a mix of yellow and black balls. From looking inside the bucket it was evident that the number of yellow balls exceeded the number if black ones. The test was to reach inside the bucket without looking and take four balls then record the number of black balls and yellow ones. At the end of our experiment after tallying up the results, we concluded that is the yellow and black colours were genes for a certain trait that the yellow gene would be dominant while the yellow would be recessive. 

       When conducting our experiment, we had to take a number of results because they varied each time. I imagine this is what Mendel must've done when working with the pea plants in his experiment. The test must've been repeated many times to ensure results that were adequate. This is the same for really any experiment, if the conclusion that comes out of the experiment, you wish to be accurate the experiment must be repeated a few times at least.
      To conclude, if believe we can agree that without Mendel's discoveries and experiments, that the modern understanding of genetics would be different from what it is today.
