Instructions
Welcome, future geneticist! The games Geniventure and Wobbledogs both offer a playful look into the complex world of genetics, heredity, and evolution. Use your knowledge of biology (and maybe your gaming experience!) to complete the challenges below. Think critically about how these games model real-world scientific principles.
Part 1: The Science of Geniventure - Dragon Breeding
In Geniventure, you breed dragons to achieve specific traits based on Mendelian genetics. Let's test your knowledge.
1. Vocabulary Match-Up: Match the genetic term on the left with its correct definition on the right.
| A. Genotype | 1. An allele whose trait only appears when two copies are present. |
| B. Phenotype | 2. Having two identical alleles for a particular gene (e.g., HH or hh). |
| C. Allele | 3. The genetic makeup of an organism, represented by letters. |
| D. Homozygous | 4. The observable physical characteristics of an organism. |
| E. Heterozygous | 5. A version or variation of a gene. |
| F. Recessive | 6. An allele that masks the effect of another allele. |
| G. Dominant | 7. Having two different alleles for a particular gene (e.g., Hh). |
Your Answers:
- A - ___
- B - ___
- C - ___
- D - ___
- E - ___
- F - ___
- G - ___
2. Punnett Square Challenge: In dragons, the allele for horns (H) is dominant over the allele for no horns (h).
A male dragon that is heterozygous for horns mates with a female dragon that has no horns. Draw a Punnett square to predict the outcome and answer the questions below.
Draw your Punnett square in the space below:
a. What are the possible genotypes of their offspring?
__________________________________________________
b. What is the probability (in percent) that an offspring will have horns (the phenotype)?
__________________________________________________
3. Genetic Deduction: Metallic scales (M) are dominant to dull scales (m). A breeder mates two dragons, both of whom have metallic scales. In their clutch of eggs, one of the baby dragons hatches with dull scales. What must the genotypes of the parents have been? Explain your reasoning.

Part 2: The Science of Wobbledogs - Mutation & Adaptation
Wobbledogs explores genetics through mutation and environmental influence. Think about how the game's mechanics relate to real biological concepts.
1. Environment and Genes: In Wobbledogs, the food a dog eats can directly alter its physical form and the traits it passes on. In the real world, an organism's environment and lifestyle choices (like diet) typically don't change its DNA sequence. However, they can influence how genes are expressed. What is the scientific field that studies these changes in gene expression called?
__________________________________________________
2. Artificial Selection: Players often carefully choose which Wobbledogs to breed to encourage desirable traits, like a specific color, multiple wings, or a striped pattern. What is the real-world term for this process of humans selecting organisms for breeding based on specific traits? Provide one real-world example.
Term: ____________________________________
Example: __________________________________
3. Design an Adapted Wobbledog: Use the principles of adaptation to design a Wobbledog that is perfectly suited for a specific environment. Be creative!
- Environment: _________________________ (e.g., Deep Sea Trench, Volcanic Plains, Arctic Tundra)
- Key Trait 1: _________________________
- How it helps survival: __________________________________________________
- Key Trait 2: _________________________
- How it helps survival: __________________________________________________
- Key Trait 3: _________________________
- How it helps survival: __________________________________________________

Answer Key
Part 1: The Science of Geniventure - Dragon Breeding
1. Vocabulary Match-Up:
- A - 3
- B - 4
- C - 5
- D - 2
- E - 7
- F - 1
- G - 6
2. Punnett Square Challenge: Male genotype: Hh. Female genotype: hh.
| H | h | |
| h | Hh | hh |
| h | Hh | hh |
a. Possible genotypes: Hh and hh
b. Probability of having horns (phenotype): 50% (The Hh genotypes result in horns)
3. Genetic Deduction:
Both parents must have the genotype Mm (heterozygous).
Reasoning: For an offspring to have dull scales, its genotype must be 'mm'. It must inherit one 'm' allele from each parent. Since both parents display the dominant trait of metallic scales, they must each have at least one 'M' allele. Therefore, the only genotype that fits for both parents is Mm.
Part 2: The Science of Wobbledogs - Mutation & Adaptation
1. Environment and Genes: Epigenetics
2. Artificial Selection:
Term: Artificial Selection (or Selective Breeding)
Example: Any valid example, such as the breeding of different dog breeds (e.g., Corgis for herding, Greyhounds for running), creating sweeter corn from wild teosinte, or breeding dairy cows for higher milk production.
3. Design an Adapted Wobbledog: Answers are creative and will vary. The evaluation should be based on the logical connection between the chosen trait and its survival advantage in the specified environment.
Part 3: Bridging the Games - Critical Comparison
(Example answers; student responses may vary but should capture the main ideas.)
| Feature | Geniventure | Wobbledogs |
|---|---|---|
| Main Source of New Traits | Combination of existing alleles from parents (heredity). | Random mutation, often influenced by environmental factors like diet. |
| Inheritance Pattern | Follows predictable Mendelian rules (dominant/recessive alleles). | More complex and seemingly random; based on a simulated "gut flora" and genetic code that mutates. |
| Player's Role | A breeder who strategically selects parents to achieve a specific genetic outcome. | A caretaker who influences evolution by controlling diet, environment, and selective breeding. |
