WebUsing a point-mutated gene conferring leucine auxotrophy as a genetic marker, it was found that the absence of UvrA reduced the Leu+ revertants and that a second mutation in mfd reduced mutagenesis further. Moreover, the mfd and polA mutants presented low but similar reversion frequencies compared to the parental strain. WebHe stated that the tendency to reversion is often induced by a change of conditions, and in the plainest manner by crossing. To explain the genetic mechanism of reversion and many other facts pertaining to heredity, variation and development, Darwin elaborated his provisional hypothesis of Pangenesis – a developmental theory of heredity. hormonio gnrh
