My dad had curly hair (spanish looking hair), my mom had very straight native american type hair.

Me & the siblings have wavy/curly hair, boys fine, girls coarse.

But my kids? No they split back out - one nearly straight haired, one curlier than me, two are too young to tell. Their dad has straight hair but his brother is curly. It is very funny to me in a happy way because I am mixy but very white lady looking, none of the kids have my complexion, two are Very Much Lighter, two are much more tan colored, but none of them in the middle. I like having a variety pack like that.
