Question

How does transgenerational epigenetics effect natural selection, give an example to support your answer.

Answer 1

Transgenerational epigenetics effect natural selection, e : Epigenetics Increasingly occupies a pivotal position in our Underskomeling of inheritannie. Natural selection and perhaps even evolution. A survey of the pubmed alutabuse, however reveals that the Great majority (>93%) of epigenetic papers have an intra- rather than an inter- generational focus, primarly on mechanisms and disease. Approximately ~1% of pi epigenetic popers even mention the nexus of epigenetics natural selection and evolution yet when environments are dynamics (eg climate change effect) there may be an "epigenetic advantage” to phenotypic switching by epigenetic Inheritance, rather than by gene mutation. An epigenetically inherited trait can arise simultaneously in many individuals as opposed to a single individual with a gene mutation. Moreover, a transient epigenetically, modified phenotype can be quickly "sunsetted" with Individuals reverting to the original phenotype. Thus lenetic phenotype switching is dynamic and temporary can help bridge periods of environmental stress Epigenetic Inheritance likely contributes to evolution both directly or indirectly

while there is a yet incomplete evidence of direct permanent incorporation of a complex epigenetic phenotype into the genome, doubtlessly, the presence of epigenetic marker and the phenotypes the creak (which may sort quite seprately from the genotype with in a population) will influence natural selection and to drive the Collective Genutype of a population. example are as follows: - phenotypes can be epigeneheally inherited. epigenetically inherited phenotype can be neutral . adaptive or maladaptive. - variation in Genutype exists between members of a population Variation in epigenetic markers exists between members of an population.
