When there is a change in the genetic material of a somatic cell, the change is only passed to the daughter cells resulting from the mitotic division of the cell. All other cells of the body remain unaffecetd. However the extent of change depends upon when the change occurs.
For eg - If change occurs after development, only a limited number of cells will carry the genetic change. If there is a change in the genetic constitution of one of the cells in the early post-conception cell divisions, then a much larger proportion of cells in the body will also carry the same change. Such an individual is in effect a somatic mosaic. If some of the germ cells are derived from the cell with the genetic change, then the individual also has germ line mosicism and may the condition to his or her offspring.
