It has been confirmed during an interview that a person's Semblance may be similar to those of the parents. However Weiss' Semblance has nothing to so with ice/snow and the company logo is most likely a reference to the name Schnee, which means snow.

Also Cinder is not Yang's mother. Not only has this been confirmed for awhile now, but the ages don't match up. If Cinder can pass as a student, she is most likely in her mid to early 20s, meaning at most she would have had Yang at 13 years old (and that is only if Cinder is 30). As far as their powers go, because they have two different mothers, Ruby could have gotten her speed from her mother and Yang's ability could have come from her mother. However we don't know what ability their shared father has so we can't determine which power (if any) comes from which parent.
