Answer:

<h2>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. </h2>

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.  

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.

AleksAgata [21]

Answer:

Epistasis

Explanation:

In epistasis, the interaction between genes is inimical, such that one gene masks or interferes with the expression of another. “Epistasis” is a word coined of Greek roots that mean “standing upon.” The alleles that are being masked or silenced are said to be hypostatic to the epistatic alleles that are doing the masking. The cause of the biochemical basis of epistasis is a genetic pathway in which the expression of one gene is dependent on the function of a gene that precedes or follows it in the pathway.

The example of epistasis given is the pigmentation of mice. we were told that "if a mouse has two recessive alleles for coat color,  it is always albino no matter what the genotype of other genes involved in coat color"

Let say recessive allele (rr), it is always albino irrespective of other type of other genes, this is true in the stance that epistasis can be reciprocal such that either gene, when present in the dominant (or recessive) form, expresses the same genotype.
