AAARGHH!!! Do I have to do a freaking Punnett Square for everyone here?
Alright. Here's Mr. and Mrs. Hardy's genotypes:
Mom: Bb; Dad: Bb.
Now, the first time mommy and daddy flipped the willey, they had Matt, right?
__]_B_]_b__
B_]_BB]_Bb]
b_]_Bb]_bb]
It's hard to read, but that's the square. As you can see, Brown hair being the dominant gene, the chances of having a child with brown hair equalled 75%, while having a blonde child is 25%.
The second time they fucked, Matt raised some ruckus and Mrs. Hardy had to get dressed and deal with the little shit. This raised her blood pressure and caused the fluids in her uterus to become extra acidic. All of Mr Hardy's sperm sadly died on the way to the egg except for the little one with the blonde hair gene and the gene for being interested in spotfests and crappy poetry.
