How can you establish that, in a newly described species of plant, a particular phenotype is due to a chloroplast rather than a nuclear gene?
What will be an ideal response?
Mutations in chloroplast genes violate Mendel's Law of Segregation in that they show uniparental inheritance patterns. In addition, the irregular segregation of chloroplasts during cell division can result in variable segregation patterns, producing a variegated phenotype due to unequal chloroplast distribution in leaf cells.
