"older" traits are usually dominant. Dolicho it is.

Then, Dinaro-Meds, Alpine-Meds, Syrids (Dinaro-Orientalids), Alpine-Nordids are usually dolicho headed?

Not sure, but this seems to be the trend:
Dark hair > light hair
Tall height > short height
Long head > short head
Dark skin = light skin
Dark eyes = light eyes

I think only the one about height is wrong

Hmm. Not sure. But it may be that the mother's height is more dominant.

But my mother is 1.64 meters tall, my father and I are 1.87 meters tall. My sister who is 3 years older than me is 1.75 meters tall. :confused:

It is thought that brachycephalicism developed relativly reccently in a short amount of time, which suggests that it is reccesive. Receive traits generally develop later. Think about hair color; red is the most receive and developed the last.
Also the Neaderthals were not so extremly Dolicocephalic. The average index was maybe 75. Most European brachyocephalics are at most 10% more (85) so it is perfectly reasonable that an isolated population could increase in cephalic index over a relativly short period of time.
But to answer your question as with any continuous trait (height, skin color) the progeny of a Brachocephalic and a Dolicocephalic would typically be an intermediate between the two parents. Discrete traits like genetic diseases follow a different pattern. The more genes are involved with a trait the more continuous the trait is.
Mixed types always have a mean cephalic index that intermediate between their parent types.

Yet, i'm the only blonde one in the entire family. All my family is dark brown. And they had a daughter(me) with blonde hair.
me with my parents

no one has blonde hair, not even grandparents.
I agree with the head shape, long head is more dominant.
Light skin is dominant in my case.
dark eyes is more dominant imo as well.
Height, since my parents became shorter due to age, i'm the tallest now 175cm.
"older" traits are usually dominant. Dolicho it is.
Actually, Brachycephaly is more archaic. Neanderthals were brachycephalic, probably even more than alpines.
