These plants can take on characteristics from both strains depending on the traits they inherit from their parents.
Hybridization, can be useful for many different reasons. The goal is to create a strain that keeps the desirable traits while trying to eliminate less desirable characteristics.
For example indica strains can be better for cultivation because maturity time is much shorter. Sometimes growers want to breed these characteristics into sativa plants.
These plants fall somewhere in between the indica-sativa spectrum. If the hybrid strain has more characteristics of one species it’s referred to as indica or sativa dominant.
