Don't daughters tend to inherit strongly from their father's genes (vice versa for sons to mothers)? I think us kids got a little from both but my sis I seem to have closer to dad's texture (high volume, defined curls). Sis got more of Mom's fine strand texture though. But then again, she just happens to take more after Mom feature-wise than Dad (she's the last one for my Mom) unlike me (First girl & child for Dad).
I definitely didn't inherit my dad's texture. He was 3a/b, loose and wavy. All my siblings and me inherited my mom's texture-4b. Every morning my dad would wet his hair and put a dab of whatever hair grease we had in the house on his hair, brush it back into beautiful waves that curled on the ends and off to work he'd go.
