How is polyploidy different than the mutation of one or two genes

Polyploidy is different than the mutation of one or two genes because mutation in one or two genes do not involve the whole set of chromosome as in polyploidy.

Explanation:

1. Polyploidy: the condition in which a normally diploid cell or organism gain one (triploid, 3N), two (tetraploid, 4N) or more additional sets of chromosomes. Polyploidy arises as the result of total non-disjunction of chromosomes during metaphase of mitosis or meiosis, in which the chromosome are not separated during cell division.

2. Mutation: a mutation is a heritable change in the genetic material of an individual.

As given here, the mutation of one or two genes is differ than polyploidy because the polyploidy involves the whole set of chromosome white mutation can be occur in a small portion of chromosome, a single gene, two genes, or large number of genes.
