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.

Which genotype(s) and phenotype for fur length are dominant?
Which genotype(s) and phenotype for fur length are recessive?
If you have a hamster with short fur, what possible genotypes could the hamster have?
If you have a hamster with long fur, what possible genotypes could the hamster have?
Did your data support your hypotheses? Use evidence to support your answer for each test.
Test One:
Test Two:
Test Three:
Which hamsters are the parents of the mystery hamster? Include evidence to prove that they are the correct parents.
In this lab, you will investigate how organisms inherit traits.

Objectives:

explain that every organism requires a set of instructions that specifies its traits
explain the difference between dominant and recessive traits or alleles
recognize phenotype as the physical expression of the genotype
recognize genotype as the collective sum of all alleles and their specifying traits
analyze animals to demonstrate evidence of the hereditary information that is passed from one generation to another. Welcome to Hamster Haven!

We are the world's largest pet store and research facility dedicated to studying hamster heredity.

Inside we have a team of geneticists who oversee the breeding and offspring of the hamsters to ensure that we have many varieties for our customers to choose from.

Recently, our team of geneticists has been studying how hamsters inherit fur length.

You are invited to join our team to assist in the process.

Let's take a look at our geneticist notebook to learn more about how traits are inherited.Let's take a closer look at cells. Inside of each cell is a nucleus. The nucleus is like the command center for the cell and houses all of the cell's genetic material, called chromosomes. Tightly wrapped in the chromosomes are individual proteins, called genes, on strands of DNA.raits are determined by the genes the hamsters inherit.

Each hamster can inherit the trait for long fur or the trait for short fur.Let's examine the hamsters that you will be investigating today.

Select each hamster to learn more about its dominant and recessive traits.
