Your genes are a blueprint of who you
will be,
Your traits being a function of
heritability.
From 0 to 1 your traits are all
measured,
With environment and genes which both
endeavored
To explain the way that they are
expressed,
However the truth is its really complex
Traits can have multiple factors and be
polygenic,
The permutations can drive someone
manic.
Also, your genes can be pleiotropic,
Making our understanding of genetics
seem quite myopic
Genes give an outline but show only so
much,
Whether African, Irish, Italian or
Dutch,
You are also affected by where you call
home,
Influenced by environment and where
your ancestors roamed.
Nature and Nurture both working in
tandem
Result in variety that may just seem
random.
Diseases can spread in ways seeming
systemic,
But environmental factors are what make
it endemic.
Studying lifestyle and environmental
effects is a must,
Since even the healthy can be hit by a
bus
In short your genes don’t work in a
vacuum,
A predisposition does not always mean
doom.
As for what makes me me, it’s easy to
see
The traits that are expressed
individually.
My height and my hair and skin kind of
fair
But that just describes me physically.
I also have attributes harder to chart,
My love of good books, and appreciation
of art.
Genetics provide a great way to start,
But people are more than the sum of
their parts.
