Response to DNA

1.    Mendel designed the experiment between different types of peas. By breeding different types of peas together, Mendel compared the offspring of these peas and found that they have traits resembling to one of their two parents. As there are more crosses, both types of traits appear in undiluted form in the future offspring. This experiment shapes the perception of heritable variant from being blendable and ephemeral to long lasting and heritable.
