Various factors, including genetic makeup, exposure to harmful substances, other environmental influences, and age, can affect the expressivity of the genes.
Expressivity can be impacted by several elements, such as genetic makeup, exposure to dangerous substances, other environmental effects, and age. Penetrance and expressivity both have a range: People who carry the gene may or may not exhibit the trait, and when they do, the trait's expression can take many different forms. These changes are referred to as mutations, and they can build up over a lifetime. Cancers can be brought on by flaws in the genes that regulate cell division. Several genetic alterations must occur for a cell to develop cancer. Some people are born with a particular mutation, such as the breast cancer-causing BRCA1 mutation.
Additionally, exposure to environmental elements including smoking, sunshine, and radiation can result in mutations. Cells frequently can detect any damage that could result in a mutation and repair it before it becomes a fixed mutation. Within a species, mutations help to create genetic diversity.
