Epigenetic changes are those which do not involve alterations in the DNA sequence. These are caused due to interaction of the genome with the environment.
<h3>
When are alterations epigenetic?</h3>
- Epigenetic modifications or tags include DNA methylation and histone modification.
- These changes alter DNA accessibility and chromatin structure thus regulating gene expression.
- These are the reversible, heritable changes which do not change your DNA sequence, but they can change how your body reads a DNA sequence.
- These are necessary for the normal development of organisms.
- Stable, long-term epigenetic modifications involve DNA methylation.
- Flexible, short-term changes involve histone modifications, such as methylation and acetylation.

Answer:
the answer for the question is snow
Answer:
1. A monohybrid cross is a cross between first-generation offspring of parents who differ in one trait while a dihybrid cross is a cross between first-generation offspring of parents who differ in two traits
True, scientists take all the numbers and bring them down to a smaller scale. Or in your case a smaller model.
