Answer:
The correct answer is A) Histone deacetylation generally decreases gene expression.
Explanation:
Histones are the proteins that are responsible for the condensation of chromatin, which is directly linked to the capacity that a gene has to be expressed. The more condensed a gene is, the less expressible it becomes.
In order to regulate the gene expression, histones can suffer from many modifications that can change their conformation and the expressiveness of specific genes.
<u>Histone acetylation is linked with an increase of gene expression; while deacetylation and methylation decrease gene expression.</u>

Homozygous is the condition that the offsprings would have, if both their parents contribute identical versions of a gene.
<h3>What is the difference between homozygous and heterozygous ?</h3>
- Homozygous and heterozygous are terms that are used to describe allele pairs.
- Individuals carrying two identical alleles (RR or rr) are known as homozygous.
- Individual organisms bearing different alleles (Rr) are known as heterozygous.
- Homozygous produce only one type of gamete whereas heterozygous produce two types of gametes.
