alleryMendel's law of independent assortment applies to:
ATwo genes on the same chromosome
BTwo genes on different chromosomes
COnly sex-linked genes
DOnly mitochondrial genes
Answer & Solution
Correct answer: B. Two genes on different chromosomes
1. The law of independent assortment says different gene pairs separate independently during gamete formation.
2. This independence holds cleanly only when the genes lie on different chromosomes.
3. Genes on the same chromosome tend to be inherited together (linkage).
4. Mendel's pea-plant traits happened to be on different chromosomes by luck.
5. So the law of independent assortment is for two genes on different chromosomes.
6. Sex linkage and mitochondrial inheritance are separate phenomena.
