Answer:
Histone acetylation or DNA methylation.
Explanation:
The epigenetics may be defined as the genetic phenomena that might cause mutation in the organism's genome. The DNA sequence of the organisms do not get changed in epigenetics.
This phenomena is limited whether the gene is herited from the mother ot the father. The phenomena like acetylation of histones increase the gene expression. The DNA methylation and histone deacetylation at specific residues reduces the gene expression.
Thus, the answer is histone acetylation or DNA methylation.

<h3>
Tissues are a group of cells that make up organs.</h3>
<u>Explanation:</u>
<em>Cells are the smallest functional units of life. Tissues are groups of similar cells that have a common function. An organ is a structure that is </em><em>composed</em><em> of at least two or more tissue </em><em>types!</em><em> </em>
Answer:
A dominant phenotype will be expressed when at least one allele of its associated type is present, whereas a recessive phenotype will only be expressed when both alleles are of its associated type. However, there are exceptions to the way heterozygotes express themselves in the phenotype.
