Mutation is the permanent alteration on the Deoxyribonucleic Acid composition that makes up a gene. For examples the classification that differs from what is common individuals. Primarily, changes affect anywhere, range in size, and affect both single and multiple genes. Gene alterations can be classified in two significant ways the hereditary mutations and acquired mutations ( Antonarakis, Luber, Wang, Chen, Silberstein, & Luo, 2018 ). The genetic mutations are mainly inherited from the parents, and they manifest themselves throughout the individual’s life. They are slowly referred to as germline mutation as they are present in the sperm of egg. Primarily, when the egg and sperm combine the fertilized egg get DNA from both parents ( Fowler, Roush, Wise, OpenStax College, & Rice University, 2013 ). Moreover, if the DNA has mutation the child born will have mutations from each parent.
The somatic or acquired mutations take place during a person’s life. Furthermore, the variations are only present in individual cells. The changes are because of environmental factors which include radiation or error in DNA copies ( Antonarakis, Luber, Wang, Chen, Silberstein, & Luo, 2018 ). The variation from somatic mutations cannot be passed to the siblings as they do not manifest themselves in body cells and occurred during the Indi duals life.

Moreover, genetics changes that are mainly referred to as de novo mutations they can be either somatic or hereditary. In some instances, the variations take place in the sperm or egg but are neither present other cells of the individual ( Fowler, Roush, Wise, OpenStax College, & Rice University, 2013 ). The de novo mutations explain the genetic disorders that affect a child with a mutation in every cell but the family does not show history of the disorder, or the parents do not show the mutation. Moreover, a somatic mutation that takes place in a single cell during the early development of the embryo result in a situation referred to as mosaicism ( Antonarakis, Luber, Wang, Chen, Silberstein, & Luo, 2018 ). Additionally, the effects of the mosaicism depend on how many cells are affected.
