Hello

[Hanna]

Yup Fred is right, my dad has psoriasis and it is starting to show strong roots in my family with a half sister and her daughter having it along with another sister and a niece, none seem to have the amount I do. (I have a big family 6 sisters 2 of which are half, and 1 brother)

From what I've researched if 1 perant has psoriasis then there is a 1 in 10 chance of child having it.
If both perants have psoriasis then it's 50/50

by the way
