Is widow's peak dominant or recessive?

Question

I'm doing a pedigree on widow's peak for bio class and so far both my grandfathers have it, my grandmas do not.

Then my dad and his only brother do not have it.

My mom's oldest brother has it, her sister doesnt, and her and her other brother does too...then me and my three siblings to have it. I need to find the possible genotypes but can't unless I know if widow's peak is dominant or recissive....and I'm really bad at firguring that out.

Please help this is do tomorrow!!! :]

Answer 2

Did you post this in the biology section too?    You might get better results over there.

This is the genealogy section.  We research dead people here.

Answer 3

the widows peak is dominant.  so even if both parents have it there is a possibility that one of the kids doesn't have the widows peak. just studied this in science...
