If Mendel had studied the 7 traits using a plant with 12 chromosomes instead of 14, in what way would his interpretation have been different?

1. He would have discovered blending or incomplete dominance
2. He would not have discovered the law of independent assortment
3. He would have discovered sex linkage
4. He could have mapped the chromosome

Correct answer: He would not have discovered the law of independent assortment

Solution

Mendel’s law of independent assortment is easiest to infer when different traits are on different chromosome pairs. With only 12 chromosomes, there would be fewer homologous pairs than the 7 traits he studied, so some traits would likely be linked and not assort independently. That would prevent him from concluding the law in the same way.
