Question

Quizplus · Accepted Answer

The epigenome controls the expression of hereditary material, which refers to the genes that have been passed down from parent to offspring. The epigenome acts like a switch that can turn genes on or off, or increase or decrease their expression. It is influenced by a variety of factors, including environmental conditions and the activities of other parts of the cell. Recessive genes are a type of gene that is only expressed when an individual inherits two copies of the gene, one from each parent. The zygote is the first cell that forms when an egg is fertilized by a sperm, and the epigenome plays a role in determining which genes are expressed in the developing embryo. Histones are proteins that help to package DNA in the cell nucleus, and modifications to histones can affect how tightly or loosely the DNA is packed, which in turn can influence gene expression. However, they are just one of many factors that make up the epigenome.
