Answer:
Objective(s):
In your own words, what was the purpose of this lab?
In this lab report, the purpose is that hamsters carry traits fro parents.
Hypothesis:
In this section, please include the if/then statements you developed during your lab activity. These statements reflect your predicted outcomes for the experiment.
Test One: If I breed a short fur, FF female with a short fur, Ff male, then I will expect to see (all short fur; some short and some long fur; all long fur) offspring.
All short fur
Test Two: If I breed a short fur, Ff female with a short fur, Ff male, then I will expect to see (all short fur; some short and some long fur; all long fur) offspring.
Some short and some long
Test Three: If I breed a long fur, ff female with a long fur, ff male, then I will expect to see (all short fur; some short and some long fur; all long fur) offspring.
All long fur
Procedure:
The procedures are listed in your virtual lab. You do not need to repeat them here. Please be sure to identify the test variable (independent variable) and the outcome variable (dependent variable) for this investigation.
Remember, the test variable is what is changing in this investigation. The outcome variable is what you are measuring in this investigation.

Conclusion:
Your conclusion will include a summary of the lab results and an interpretation of the results. Please write in complete sentences.
1. Which genotype(s) and phenotype for fur length are dominant? FF
2. Which genotype(s) and phenotype for fur length are recessive? ff
3. If you have a hamster with short fur, what possible genotypes could the hamster have? It would probably be Ff or a ff
4. If you have a hamster with long fur, what possible genotypes could the hamster have? It would be Ff or an FF
5. Did your data support your hypotheses? Use evidence to support your answer for each test.
◦ Test One:? ◦ Test Two:?
