TR 3.2: Gathering Evidence about Inheritance

Objective: KWBAT investigate how genes inherited during sexual reproduction cause offspring to have different gene combinations, and they use the digital model to gather evidence to support or refute a claim about inheritance.
Part 1

Part 1: Do Now

In this unit, you have been investigating the following question: Why do traits for silk flexibility vary within this family of Darwin’s bark spiders?

Review claim 2, which is listed below. This claim provides one possible response to this question.

Claim 2: The offsprings’ traits depend on which parent the offspring inherited more copies of genes from.
0

Do you agree or disagree with this claim?

Explain why you either agree or disagree with the claim. Use what you have learned about genes and inheritance to explain your thinking.

Sentence Starter:
I (agree/disagree) with this claim because...

1

What determines how a protein will function?

1

TRUE or FALSE: If two fish have different body colors, it’s because they have different gene versions for body color. This means their proteins have different instructions and function differently.

1

Two penguins were raised in different environments. They have different traits for feather density. Why do they have different traits for feather density?

Open up the simulation as soon as you finish your Warm-Up! You will need it for the later parts of the lesson.

Part 2: Second Read of Twins Article

So far, we know that an organism’s genes provide instruction for making proteins, and that proteins are what determine an organism’s traits. But how do organisms get those genes in the first place?



We’re going to support this key concept with evidence from the article we read yesterday.

Find a quote that answers this question:

What happens if a parent has two different versions of one gene?

0

Once fertilization happens, all gene combinations will end up the same no matter what. Sperm Cells and Eggs will always combine the same way. There is no such thing as genetic variation.

Is this true? Explain your reasoning.

Sentence stater:
This is (true/not true) because...

0

How does this portion of the article explain how organisms get their genes and why are gene combinations different in offspring? Use a quote from the article as evidence to support your answer.

Sentence Starter:
Organisms get their genes through...
Gene combinations are different in offspring because...

Part 3: Evaluating Evidence from the Sim

0

Evaluate: Is this true? Do offspring inherit more copies of a gene from one parent than another?

  1. Launch the Sim
  2. Press BODY COLOR to observe Otis and Anne’s traits and gene versions for this feature. Record your observations in the first table.
  3. Mate Otis with Anne by moving Anne over Otis until a dotted circle appears.
  4. Press CREATE REPRODUCTIVE CELLS. Once the reproductive cells have been created, press RANDOMLY FERTILIZE. Observe as the egg and sperm cells come together to create new offspring.
0

PARENTS:

Observe Otis and Anne’s traits and gene versions for BODY COLOR. Record your observations in the table.

0

OFFSPRING:

Examine the traits and combinations of gene versions for each offspring. Then, record your observations in the second table below.

1

How many gene versions did each offspring get from their father?

1

How many gene versions did each offspring get from their mother?
