Heredity Lab Report Instructions: In the Heredity lab, you investigated how hamsters inherit traits from their parents.
Record your observations in the lab report below. You will submit your completed report.
Name and Title:
Include your name, instructor's name, date, and name of lab.
Objective(s):
In your own words, what was the purpose of this lab?
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.
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.
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.
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.
Test variable (independent variable):
Outcome variable (dependent variable):

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?
2. Which genotype(s) and phenotype for fur length are recessive?
:
short fur : long fur
3. If you have a hamster with short fur, what possible genotypes could the hamster have?
4. If you have a hamster with long fur, what possible genotypes could the hamster have?
5. Did your data support your hypotheses? Use evidence to support your answer for each
test.
