TR 2.4: Applying Ideas About Genes

Objective: KWBAT construct models to explain how gene variations at the molecular scale cause variations at the macroscale.
Part 1

Part 1: Review


The image of the sim has a few key terms blacked out. Fill out the missing information!

Silk flexibility, silk stickiness, and venom are all examples of...

“F1” and “F2” represent two different...

Leo has a medium silk flexibility; this is an example of a....

Leo is ______ for this feature

Part 2

Part 2: Modeling Variation in Spider Offspring


So far in this unit, we’ve been trying to understand the following question: Why do Darwin’s bark spiders make different proteins for silk flexibility?

Using what you’ve learned so far, answer that question, using the terms proteins, heterozygous, and homozygous.

Sentence Starter:
Darwin Bark Spiders make different proteins for silk flexibility because...

Use the image above to answer questions 6 - 18.

What protein should be in this box?

What protein should be in this box?

Offspring A is __________, this means they have __________version(s) of this gene. Because they have __________ versions of this gene, their cells will have __________ types of protein(s).

OFFSPRING A -

Explain how the proteins connect to make the trait for silk flexibility.

Hint:
1. Genes = ?
2. Are they homozygous/heterozygous?
3. What does that mean for proteins?
4. How do they connect?

Sentence Starter:

Offspring __ is ____because he has (one/two) copies of the gene. Allele ___ instructs for Protein ____ (and allele ___ instructs for Protein ____. This means that ______

(talk about how the proteins connect - how many connectors and what that means for the type of silk flexibility)

Offspring B is __________, this means they have __________version(s) of this gene. Because they have __________ versions of this gene, their cells will have __________ types of protein(s).

OFFSPRING B -
Explain how the proteins connect to make the trait for silk flexibility.

Hint:
1. Genes = ?
2. Are they homozygous/heterozygous?
3. What does that mean for proteins?
4. How do they connect?

Sentence Starter:
Offspring __ is ____because he has (one/two) copies of the gene. Allele ___ instructs for Protein ____ (and allele ___ instructs for Protein ____. This means that ______


(talk about how the proteins connect - how many connectors and what that means for the type of silk flexibility)

Offspring C is __________, this means they have __________version(s) of this gene. Because they have __________ versions of this gene, their cells will have __________ types of protein(s).

OFFSPRING C -
Explain how the proteins connect to make the trait for silk flexibility.

Hint:
1. Genes = ?
2. Are they homozygous/heterozygous?
3. What does that mean for proteins?
4. How do they connect?

Sentence Starter:
Offspring __ is ____because he has (one/two) copies of the gene. Allele ___ instructs for Protein ____ (and allele ___ instructs for Protein ____. This means that ______

(talk about how the proteins connect - how many connectors and what that means for the type of silk flexibility)

Offspring D is __________, this means they have __________version(s) of this gene. Because they have __________ versions of this gene, their cells will have __________ types of protein(s).

OFFSPRING D -
Explain how the proteins connect to make the trait for silk flexibility.

Hint:
1. Genes = ?
2. Are they homozygous/heterozygous?
3. What does that mean for proteins?
4. How do they connect?


Sentence Starter:
Offspring __ is ____because he has (one/two) copies of the gene. Allele ___ instructs for Protein ____ (and allele ___ instructs for Protein ____. This means that ______

(talk about how the proteins connect - how many connectors and what that means for the type of silk flexibility)
