A recent study looked at data
from people and their parents to try and quantify how genes not acquired from the
parents still influenced the individual. A mother diagnosed with anxiety will affect
the environment she creates for her daughter even if this trait is not passed
down to the daughter. They found that combined, the variants that weren’t
passed down had an effect about 30% as big as the genes that were passed down. Genetic
nurture is an important aspect when it comes to parenting, and different
parents provide different types of nurture. How a parent provides nurture
however is related to the parent’s behavior which is ultimately affected by
their genes. Although this study focused on one person and their parents this
might be a chain of passed traits as parents are influenced by parents as the
chain continues.
