Answer:
The saddle joint that can be found in the thumbs ensures that it moves from side to side and rotate on its own axis alone.
The saddle joint allows movement in different directions but only a small amount of rotation. The thumb is the only organ that has a saddle joint.
It should be noted that the bones that are in the saddle joint ensure the back and forth movement of the thumbs.
The pivot joint is the joint that's responsible for ensuring that one bone rotates around another bone. Ball and socket joint can be found in the shoulder and the hip and it allows for greater freedom of movement.
When compared to other movable joints, the saddle joint is prone to dislocation because it's free-moving and rotates on its own axis alone.
In conclusion, if the thumb contained a pivot joint or a ball and socket joint, it'll be able to move more freely.
I hope this helps! :)

La genética se puede definir como el estudio de la herencia. Resulta de vital importancia dado que es la forma por la cual se determinan las características de cada uno de los individuos. Los padres transmiten a sus hijos ciertos genes que son los responsables de su estatura, del color de su cabello, del color de la piel, del color de los ojos. De la misma manera la predisposición a padecer ciertas enfermedades puede estar vinculada con la herencia genética recibida por los progenitores.
