For example, brachydactyly is fatal when the genetic defect is expired during infancy in homozygous recessive individuals. A mutagen is a compound that might be chemical or physical in nature and cause changes in the genetic material which are heritable and irreversible. Acquired (or somatic) mutations occur at some time during a person's life and are present only in certain cells, not in every cell in the body. Mutations arise spontaneously at low frequency owing to the chemical instability of purine and pyrimidine bases and to errors during DNA replication.
