Linked Genes and Recombination
Advanced Punnett

Since the linked genes don't separate...

only 2 types of gametes can be produced. This makes the punnett square much easier to write out.

Let's say Mr. and Mrs. Smiley both have the genotype ET/et. That means they are both hybrids, BUT they have only 2 types of gametes: ET and et. So instead of a 4 by 4 punnett square, you get a 2 by 2 punnett square:

  instead of this...   we get this...
