Science & Mathematics - 15 July 2007

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?

Need homework help:

Don't have to do all of them, just please show me your steps.

I purchased a window a/c unit not realizing it until I got it home. It is a 12,000 btu bad boy and I got it on sale, so I kinda don't want to return it. But I inspected some through the wall units and I don't see much difference.

If I remove the housing on the window a/c and stick it in the wall, that should work properly, right? What do you think?

I know, I know, another one of these dumb questions.

But seriously, not like a small little living bacteria or anything. Is there anything out there like on mars or any other planet that has a living life form as intellegent or even more that us? That would be pretty cool.
