are the Genes "Leaders" or "Followers" or both???...

[Koni]

I first had read the Books from Richard Dawkins like "The Selfish gene"...

Now I am reading the Book: "Developmental Plasticity and Evolution" from Mary Jane West-Eberhard...

At how much percent % predetermine us our Genes and in how much percent % determines us the Enviroment???...

Have we some evidence from a trait that can be influenced from both und do we know the underlaying biochemical pathway???...

Which is the key factor on an Organism???... The Genotype or the Phenotype???...

 

[CharonY]

Almost all traits fall into the both category. Genes generally code for proteins and their combines biochemical actions result in cellular and organismal phenotypes. However, they react to feedback, such as e.g. availability of nutrients. When a cell lacks the appropriate amino acid certain proteins cannot be produced without activation of anabolic pathways to synthesize those, for example. Genes always act in the context of their cellular environment.

Bad/poor adaptation to environment means instant death. Intelligent life forms can change it because of using artificial protections like astronaut suits.

Organisms (requiring Oxygen) living at high mountains (high altitudes) have to adopt to low Oxygen presence, the all organisms that won't do it, will die (natural selection).

You said "predetermine us" and then later "determines us".. Did you mean "us" = "the all living organisms" (not just humans).. ?

I meant all living organisms (with us too)...

I keep in mind that: Genes always act in the context of their cellular environment!!!...

(THANK You both for your comments!!!...)
