Epigenetics (as in "epigenetic landscape") was coined by C. H. Waddington in 1942 as a portmanteau of the words genetics and epigenesis.[4] Epigenesis is an old[5] word which has more recently been used (see preformationism for historical background) to describe the differentiation of cells from their initial totipotent state in embryonic development. When Waddington coined the term the physical nature of genes and their role in heredity was not known; he used it as a conceptual model of how genes might interact with their surroundings to produce a phenotype.
I would like you to know that I copied this off of Wikipedia. Just giving them the credit they deserve.

How can 2 plants cells from the same plant have different structures and functions?
Different genes are expressed (see - epigenetics).
What is the relationship between evolution and epigenetics?
A few years ago, biologists would have said that the relation between epigenetics and evolution was minimal, given that there was no reason to think, at the time, that epigenetic effects lasted more than a couple of generations. Now, however, it is becoming more apparent that epigenetic factors can indeed influence the way allele frequencies develop over the generations, and thus have a lasting impact on the evolution of a population.
Does inheritance of acquired characteristics express the concept of natural selection?
No. Natural selection is the differential reproductive success of varying inherited traits. Acquired traits do little to affect the inheritance of traits, except through epigenetics.
When did John Dice discovered jaundice?
It was actually been discovered for thousands of years! John Dice just discovered it but it was discovered for thousands of years. :)
Where was kinetic energy discovered?
It Was First Discovered When Issac Newton Was At War Then He Shocked One Of His Men And He Realize That It WasKentic Energy.He Also Discovered It In 1977.It Was Discovered In The Stae Lincolnshire England .He Was From There To.
What is epigenetics as it relates to psychology?
Epigenetics in psychology refers to the study of how environmental factors can influence gene expression and behavior without changing the underlying DNA sequence. This field explores how experiences such as stress, trauma, or parenting can lead to changes in gene activity that may affect mental health, cognition, and overall psychological well-being.
The study of how environmental factors influence the expression of genes without altering the DNA is known as?
its called epigenetics
What can influence your influence?
environmental factors e.g. epigenetics
What factors influence epigenetics?
Extreme environmental conditions influence epigenetics. There are certain chemical compounds adhering to the genetic material but not altering the DNA sequence during conditions of stress to the organism. For example proline protects the plants from wilting during conditions of drought.
How can 2 plants cells from the same plant have different structures and functions?
Different genes are expressed (see - epigenetics).

What genetic factors might be responsible for a change in an organism's body plan?
The importance of genetic factors has recently been at least halved by the discovery of Epigenetics.
Which idea did lamarck propose that was rejected by his fellow scientists?
That organisms pass on traits acquired in their lifetimes. It was rejected in favour of Darwinian evolution, in which species and not individuals evolve, but Larmarckism is valid to a point where epigenetics is concerned.

What are recent topics forTerm paper in cell biology?
Try epigenetics... its the study of silencing and activating genes. Very interesting and will soon be the forfront of this "wave of information" everyone is talking about
