Question

Quizplus · Accepted Answer

Mendel's experiments with pea plants showed that certain traits, such as flower color or seed shape, are inherited as distinct units that do not blend with each other. This supports the idea that hereditary units are discrete and passed down from parent to offspring in a predictable manner.

B) blend with one another  
 Mendel's experiments actually demonstrated the opposite of blending inheritance. He found that certain traits were not intermediate between the parents, but instead followed predictable patterns of inheritance based on discrete units passed down from each parent.

C) are composed of DNA  
 Mendel did not propose or discover the role of DNA in inheritance. This was not known until much later, through the work of other scientists such as Watson and Crick.
