Daily Agenda: 1. Warm up - 15 minutes 2. Frankenfish Activity - 45 minutes 3. Finish Pedigree WebQuest - 30 minutes

Objective: 3.03 Interpret and predict patterns of inheritance.

Directions for Frankenfish Activity: 1. You need a coin of any kind – if you do not have a coin, cut a circle of paper and write heads on one side and tails on the other. 2. For each of the traits in the table, flip the coin twice (once for mother and once for the father). If the coin is heads, circle the capital (dominant) allele and if it lands on tails, circle the small (recessive) allele. Ex. For Body Shape, I flipped once and got heads so I circled the B under father. I flipped again and got tails so I circled the b under mother. 3. Copy the letters that you circled into baby genotype – in the example above, I would write Bb. 4. Determine the phenotype from the genotype that you just wrote for the baby – use the phenotype chart on the page. In the example above, the genotype Bb would give the fish a long & straight body. 5. Continue this for all of the 8 traits that your fish will inherit. 6. Draw your fish on a sheet of plain paper. 7. Turn to the back of the paper and complete the table with your fish’s information. 8. Get the genotype and phenotype information for someone else’s fish and then complete the 8 punnett squares to simulate those fish having babies.
