Acquired characters do not produce change in the DNA of germ cells, so they cannot be inherited. Only those characters which have a gene for them can be inherited. Acquired traits are synonymous with acquired characteristics. They are not passed on to offspring through reproduction. The changes that constitute acquired characteristics can have many manifestations and degrees of visibility, but they all have one thing in common. An inherited trait is genetically determined. Inherited traits are passed from parent to offspring according to the rules of Mendelian genetics. Most traits are not strictly determined by genes but rather are influenced by both genes and the environment.
