Epigenetics. You have the basic coding, but there is an auxillary coding overlay top of your basic genetic makeup that can modify across generations in response to environment.

From:

https://en.wikipedia.org/wiki/Epigenetics

"Epigenetics is the study of heritable changes in gene function that do not involve changes in the DNA sequence.[1] The Greek prefix epi- (ἐπι- "over, outside of, around") in epigenetics implies features that are "on top of" or "in addition to" the traditional genetic basis for inheritance.[2] Epigenetics most often denotes changes in a chromosome that affect gene activity and expression, but can also be used to describe any heritable phenotypic change that does not derive from a modification of the genome, such as prions. Such effects on cellular and physiological phenotypic traits may result from external or environmental factors, or be part of normal developmental program. The standard definition of epigenetics requires these alterations to be heritable,[3][4] either in the progeny of cells or of organisms."

Its probably Scientific for me to say that I am overweight because my mother did not eat much in the depression. (And not, of course, her fault.)

I think of it as stuff just waiting to happen, when the right thing turns on the gene’s switch.

IN other words, Lysenkoism may have some limited legitimacy.

Well put.
