If you have an isolated species bred specifically for certain physical attributes by humans over a period of even a few decades does that damage all manner of genetic and anatomical systems in animals? *Can someone please answer the question? This is my 2nd time asking.*

no

Explanation:

this is because you breeding the species does not stop the life of the species in other areas and the purpose of you breeding it is to notice some of its features in the absence of physical factors

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.

i think it is dna, i'm not totally sure but i think it might be.
