Across
3. The observable physical traits of an organism, like a drake's scale color or a dog's leg count.
5. A change in the DNA sequence, a core mechanic for generating new traits in Wobbledogs.
7. The process of cell division that produces gametes (sperm and egg cells) in Geniventure's drakes.
8. The genetic makeup of an organism, represented by letters like 'Tt'.
Down
1. Different versions of a gene, such as the ones for horns or no horns.
2. A diagram used to predict the potential genotypes of offspring from a genetic cross.
4. The microorganisms in a Wobbledog's gut that influence its mutations.
6. When humans (or players) intentionally breed organisms for desired traits. Also known as artificial selection.
Part 2: The Drake vs. The Dog - A Comparative Analysis
Both Geniventure and Wobbledogs model genetic principles, but in very different ways. Fill in the table below to compare them. Then, answer the critical thinking question.
| Genetic Concept | Geniventure (Drakes) | Wobbledogs |
|---|---|---|
| Inheritance Mechanism (How are traits passed down?) |
||
| Source of New Traits (How do new variations appear?) |
||
| Player's Role in Genetics (How do you influence the outcome?) |
Critical Thinking: Which game do you think provides a more scientifically realistic (not necessarily better) model of how genetics and evolution work in the real world? Explain your reasoning, considering both the strengths and weaknesses of each game's model.

Part 3: Wobbledog Selective Breeding Plan
Scenario: Your goal is to breed a Wobbledog with two specific traits: striped fur and a very long body. Starting with a pair of default dogs, describe a plausible, step-by-step plan based on Wobbledogs' game mechanics to achieve your goal. Be specific!
- What kinds of foods would you prioritize feeding your dogs and why?
- How would you use the breeding simulation to select for your desired traits?
- What is a major challenge or setback you might encounter, and how would you overcome it?
Your Plan:

Part 4: Geniventure Dihybrid Cross Challenge
In Geniventure, dragon traits follow Mendelian genetics. Let's analyze a complex cross.
- The allele for Wings (W) is dominant over the allele for no wings (w).
- The allele for Metallic scales (M) is dominant over matte scales (m).
You want to cross a drake that is heterozygous for both traits (WwMm) with a drake that has no wings and matte scales (wwmm).
1. Determine the possible gametes that each parent can produce.
Parent 1 (WwMm) Gametes: _______, _______, _______, _______
Parent 2 (wwmm) Gametes: _______, _______, _______, _______ (Note: There is only one unique type)
2. Complete the Punnett square to predict the genotypes of the offspring.
3. Analyze the results: Based on your Punnett square, what are the predicted phenotypic ratios of the offspring?
_______ (Wings, Metallic scales) : _______ (Wings, matte scales) : _______ (No wings, Metallic scales) : _______ (No wings, matte scales)

Part 2: The Drake vs. The Dog - A Comparative Analysis
(Note: Student answers will vary but should contain these key ideas.)
| Genetic Concept | Geniventure (Drakes) | Wobbledogs |
|---|---|---|
| Inheritance Mechanism | Follows clear, predictable Mendelian rules (dominant/recessive alleles). Traits are inherited directly from parents' alleles. | A mix of parental genetics and environmental influence. Gut flora, influenced by diet, directly mutates the dog's genes, making it less predictable. |
| Source of New Traits | New traits come from combining existing alleles from different parents. Specific mutations are sometimes introduced as a puzzle mechanic. | Primarily from constant, diet-influenced random mutations. Breeding combines existing genes, but mutation is the main driver of new forms. |
| Player's Role in Genetics | Solve puzzles by selecting specific parents to breed to achieve a target genotype/phenotype. It is very goal-oriented. | Influence genetics indirectly by controlling diet (affecting gut flora and mutations) and directly by choosing which dogs to breed. It is more experimental. |
Critical Thinking: A good answer might argue that Wobbledogs is more realistic. Real-world evolution is driven by a combination of inheritance, environmental pressures (like diet), and random mutation, which Wobbledogs simulates well. Geniventure is a fantastic tool for teaching Mendelian genetics, but it's a simplified model. Real genetics are far more complex than simple dominant/recessive traits, and the constant, somewhat random change in Wobbledogs better reflects the messy, unpredictable nature of real biological systems.
Part 3: Wobbledog Selective Breeding Plan
(Example Answer)
My plan would be to separate my dogs to focus on one trait at a time. I'd feed one group of dogs foods that increase the chance of striped patterns (like certain seeds). I'd feed another group foods that tend to make dogs longer (like burritos). Once I have a striped dog and a long dog, I would breed them together. The major challenge is that mutations are random; I might get undesirable traits like extra eyes or weird legs. If this happens, I would breed the offspring with a more "normal" dog or one that has the other trait I want, hoping to select for the good traits and breed out the bad ones over several generations.
Part 4: Geniventure Dihybrid Cross Challenge
1. Parent Gametes:
Parent 1 (WwMm) Gametes: WM, Wm, wM, wm
Parent 2 (wwmm) Gametes: wm, wm, wm, wm (all are the same)
2. Completed Punnett Square:
| WM | Wm | wM | wm | |
| wm | WwMm | Wwmm | wwMm | wwmm |
(Note: Since all gametes from Parent 2 are 'wm', the student only needs to fill out one row to find the ratio.)
3. Phenotypic Ratios:
The genotypes are WwMm, Wwmm, wwMm, and wwmm in a 1:1:1:1 ratio.
The corresponding phenotypes are:
1 (Wings, Metallic scales) : 1 (Wings, matte scales) : 1 (No wings, Metallic scales) : 1 (No wings, matte scales)
