mating
It has been observed that traits differ with respect to their action in
mating. Given a specific type of trait-mating, say of a trait with like
trait, or trait with the lack of that trait, some types always reappear
in the next generation or else are lost entirely from the family line
unless reinfused, whereas other types of traits may not reappear in the
next generation, but still appear in a generation further removed.
Another type of trait is transmissible only by one sex of a family line,
and can not be transmitted by the other sex.
