Mouse Genetics (One Trait)
Breed "pure" mice with known genotypes that exhibit specific fur colors, and learn how traits are passed on via dominant and recessive … genes. Mice can be stored in cages for future breeding, and the statistics of fur color are reported every time a pair of mice breed. Punnett squares can be used to predict results.

Mouse Genetics (Two Traits)
Breed "pure" mice with known genotypes that exhibit specific fur and eye colors, and learn how traits are passed on via dominant and … recessive genes. Mice can be stored in cages for future breeding, and the statistics of fur and eye color are reported every time a pair of mice breed. Punnett squares can be used to predict results.

Chicken Genetics
Breed "pure" chickens with known genotypes that exhibit specific feather colors, and learn how traits are passed on via codominant … genes. Chickens can be stored in cages for future breeding, and the statistics of feather color are reported every time the chickens breed. Punnett squares can be used to predict results.

Hardy-Weinberg Equilibrium
Set the initial percentages of three types of parrots in a population and track changes in genotype and allele frequency through … several generations. Analyze population data to develop an understanding of the Hardy-Weinberg equilibrium. Determine how initial allele percentages will affect the equilibrium state of the population.
-
Microevolution
Observe the effect of predators on a diverse population of parrots. The initial percentages and fitness levels of each genotype can be … set. Determine how initial fitness levels affect genotype and allele frequencies through several generations. Test predictions about what initial conditions lead to equilibrium, and which lead to extinction.

Evolution: Mutation and Selection
Observe evolution in a fictional population of bugs. Set the background to any color, and see natural selection taking place. Inheritance … of color occurs according to Mendel's laws and probability. Mutations occur at random, and probability of capture by predators is determined by the insect's camouflage.

Evolution: Natural and Artificial Selection
Observe evolution in a fictional population of bugs. Set the background to any color, and see natural selection taking place. Compare … the processes of natural and artificial selection. Manipulate the mutation rate, and determine how mutation rate affects adaptation and evolution.

Building DNA
Construct a DNA molecule, examine its double-helix structure, and then go through the DNA replication process. Learn how each component … fits into a DNA molecule, and see how a unique, self-replicating code can be created.

RNA and Protein Synthesis
Go through the process of synthesizing proteins through RNA transcription and translation. Learn about the many steps involved in … protein synthesis including: unzipping of DNA, formation of mRNA, attaching of mRNA to the ribosome, and linking of amino acids to form a protein.

DNA Fingerprint Analysis
Perform DNA scans on frogs to learn how differences and similarities in the scans can be used to identify physical characteristics of … the frogs. This technique of scanning is what provides the "DNA fingerprint," which is becoming more commonplace in today's society. The DNA of twin frogs can also be studied to see how the scans compare.
-
Human Karyotyping
Sort and pair the images of human chromosomes obtained in a scan. Find differences in the scans of the various patients to find out … specific things that can cause disease, as well as the gender of the person.
