Part 3: Problem Solving Scenarios
Apply your knowledge to solve these in-game challenges.

Geniventure Dragon Breeding: In Geniventure, the allele for fire-breathing (F) is dominant over the allele for not breathing fire (f). You are asked to breed a male dragon that is heterozygous for the trait (Ff) with a female dragon that cannot breathe fire (ff).
A. Complete the Punnett square below to predict the possible genotypes of their offspring.
f f F f
B. What is the percentage chance that an offspring dragon will be able to breathe fire?
-
Wobbledog Wonders: Your goal is to create a colony of Wobbledogs with extremely short legs. You notice that when you feed your dogs "Donut Holes," their legs tend to get shorter during their pupation (growth) stage. The game's mechanics state that mutations are influenced by the gut flora, which is determined by diet.
Describe a strategy, spanning at least two generations, to achieve your goal of a short-legged Wobbledog colony. Explain how the environment (diet) influences the heritable traits (genetics) in this scenario.
Part 4: The Bigger Picture
In both Geniventure and Wobbledogs, the player actively decides which individuals get to breed to create offspring with specific traits. As you learned in Part 1, this is called artificial selection. How does this process differ from natural selection, which drives evolution in the wild? Provide one real-world example of an organism that has been significantly shaped by artificial selection.

Part 2: Compare the Mechanics
(Answers may vary slightly but should reflect these core ideas.)
| Feature | Geniventure | Wobbledogs |
|---|---|---|
| Primary Source of New Traits | Combining alleles from parents through breeding (recombination). Mutations are rare and scripted. | Constant mutations heavily influenced by the dog's diet and resulting gut flora. |
| Predictability of Offspring | High. Follows predictable Mendelian genetics (e.g., Punnett squares). | Low. While genetics play a role, the diet-based mutations make outcomes chaotic and surprising. |
| Influence of Environment | Minimal to none. Genetics are predetermined and not affected by the dragon's surroundings. | Very high. The environment (specifically, the food the dog eats) is the primary driver of genetic change (mutation). |
Part 3: Problem Solving Scenarios
- Geniventure Dragon Breeding:
A. Completed Punnett Square:
f f F Ff Ff f ff ff B. There is a 50% chance. The two offspring with the genotype Ff will be able to breathe fire, while the two with ff will not.

Wobbledog Wonders:
(Example Answer)Generation 1: I would feed all my current dogs "Donut Holes" to influence their gut flora. This directly affects their phenotype, causing their legs to become shorter as they grow. When they are adults, I would select the male and female dogs with the absolute shortest legs to breed with each other.
Generation 2: I would take the eggs from the first breeding pair and raise the resulting puppies. I would feed this new generation exclusively "Donut Holes" as well to further encourage the short-leg mutation. Once they mature, I would again select the individuals with the shortest legs to breed. By repeating this process, I am using the diet (environment) to influence mutations and then selecting for the desired trait, hopefully making the short-leg genes more common and pronounced in my colony's gene pool.
Part 4: The Bigger Picture
(Example Answer)
Difference: In artificial selection, humans are the selecting agent. We choose which individuals reproduce based on traits that we find useful or desirable (e.g., more milk from a cow, a specific color in a flower). In natural selection, the environment is the selecting agent. Individuals with traits that make them better suited to survive and reproduce in their specific environment are more likely to pass on their genes. The goal is survival and reproduction, not fulfilling a human desire.
Real-world Example: Domestic dogs are a prime example of artificial selection. All breeds, from Great Danes to Chihuahuas, descended from a common wolf-like ancestor. Humans selectively bred them for thousands of years for specific traits like size, temperament, and hunting ability. Other valid examples include most farm animals (cows, chickens) and agricultural crops (corn, bananas, broccoli).
