alleryStart learning →Mendel deliberately chose characteristics such as violet against white flowers. What kind of variation is that?
ACodominant variation
BContinuous variation
CDiscontinuous variation
DQuantitative variation
Answer & Solution
Correct answer: C. Discontinuous variation
1. Violet and white are two distinct classes with nothing in between.
2. Traits inherited in distinct classes show discontinuous variation.
3. Because the classes are distinct, Mendel could see that traits kept their distinctness and were not blended.
4. Continuous variation would have hidden that result behind a smooth range of colours.
5. Codominance is a pattern of allele expression, not a category of variation.
