This has been plaguing me for a while. In the show, "Little People, Big World" the Roloff Family is comprised of two dwarf parents, one dwarf son, and three normal size children. Now from what I've learned in genetics class (and my little internet research) dwarfism comes from a recessive gene. That means that for someone to be a dwarf phenotypically, they have to possess two dwarf genes and no "normal size" genes, because even one "normal size" gene will result in the child being of normal size. But the Roloffs, who are both dwarfs, have not one, but THREE normal sized kids.
How is this genetically possible?
