All of the following would be associated with mutations in a gene, EXCEPT?Genetic variationAdditive genesMultiple allelesTruncated proteins

Additive genes would not be associated with mutations in a gene.

Here's why:

1. Genetic variation: This is directly associated with gene mutations. Genetic variation refers to the differences in genes among individuals and populations. Mutations, which are changes in the DNA sequence of a gene, are one of the main sources of genetic variation.

2. Additive genes: These are genes that work together to influence a trait. Each additive gene adds a small amount to the trait. This is not directly associated with gene mutations. A mutation in a single gene would not necessarily affect the additive effect of multiple genes on a trait.

3. Multiple alleles: This refers to the existence of more than two alleles for a particular gene within a population. Mutations can lead to the creation of new alleles, so this is associated with gene mutations.

4. Truncated proteins: These are incomplete protein structures that can result from gene mutations. If a mutation occurs that causes the protein-coding process to stop prematurely, a truncated protein can be produced. So, this is also associated with gene mutations.
