Explain Mendel's conclusion that traits passed from parents to offspring are not blended, but are instead inherited as if they are separate units
What will be an ideal response?
Mendel based his conclusion on several observations. Only one of the parental traits was present in the offspring (F1). The trait not present in the offspring (F1) reappeared in about 25% of the second offspring generation (F2). In all crosses, it did not matter which parental plant contributed the pollen; the results were always the same. He, therefore, concluded that traits remained unchanged, even though they might not be expressed in a specific generation. Instead, he concluded that traits were inherited as if they were separate units that did not blend together.
