I have a lot of tall people in my family. How about you?
1_Wizard
We range in height.  There is a particular genetic profile in men that is correlated with height.
0_Apprentice
Oh, is it the same with women?
1_Wizard
No, in the male is the Y haplotype I-M170.

My boyfriends family has a bunch of tall women. I wonder if they also have a certain gene.
1_Wizard
Perhaps.  As the frequency of the Y haplotype increases the average male height rises, so why not the female height too?

Yes, that is what I am thinking. There has to be something genetic about it.

Oddly, in my family all the girls were short and all the boys were tall!  Height by gender measured from the bottom of our feet to the top of our head.

That is interesting. Maybe there are two different genes passed down based on gender.
