Several means exist to measure genetic divergence,
but Wright’s coefficient of relationship is not such a means
or is at best only an approximation of genetic relatedness
because a coefficient of relationship
does not use genetic tests
and when two living things produce an offspring by meiosis
each chromosome is taken from only one parent at random.
This is why siblings are different from each other;
it’s not half of each parent; it’s random.
Being a Native American poet
I am a proud card-carrying member
of a federally recognized tribe;
however, my father was not an Indian.
Only a genetic test could determine
whether all my blood is Indian, like Mom,
or none of it is, like Dad.
If I were a Calvinist Indian,
tribal membership would be like a Boy Scout merit badge;
I would need to demonstrate a native inheritance.
I had a friend who said that I was
not an Native American poet because of what I write about
but because I am a Native American.
According to Mendel’s law of independent assortment,
“The zygote will normally end up with 23 chromosomes pairs,
but the origin of any particular chromosome will be randomly selected
from paternal and maternal chromosomes.
This contributes to the genetic variability of progeny.”
