This document appears to be notes from a biology class lesson on heredity and genetic traits. It includes: 1) Bell work questions about alleles, examples of cross breeding, and what is stored in chromosomes. 2) An activity where students read an article about apple breeding and discuss observed traits and examples of cross-breeding. 3) An activity where students examine each other and list observed traits, and then vote on a class pet to use as an example for learning about heredity of traits. 4) A discussion where students design an imaginary "designer pet" by selecting 7 traits from different animals to combine into a new species, drawing the pet, naming it, and explaining the

1. Bell Work
1) Which one of these moths is
heterozygous?
2) What is the recessive allele in
this situation?
3) What is the phenotype of
moth B?

1) Define allele in your own words. Give an example
2) Give an example of cross breeding
3) What is stored in a chromosome?

4. Welcome!
 Itinerary
 Bell Work
 Finishing Vocab
 Defining our standard
 Reading article
 Heredity: Inheritance and Variation of
Traits – Traits activity
 Mark your Agendas:
 ManipulatAIRS Lab report DUE
Tuesday. Labs turned in late
today are now 10% off. Who still
needs to turn in? Lets see.
 By the end of today you should :
 Be familiar with the language of heredity
or be able to access sources that enable
you to learn unit vocabulary

5. Quizlet Guess and Check

6. Clarifying Traits vs. Alleles
Recall that a trait is
Alleles are
Ex:
Earwax – wet or dry?
A characteristic that an organism can pass on to its offspring through its genes.
Alternative forms of a gene for each variation of a trait of an organism.

7. Choosing a base pet

8. Article Discussion
What were some of the traits listed in the article?
Can you give an example of a cross-breed in this article?

9. Determining Traits
Look at the person across from you
Give them a high give. (Fist bump if you are super hip…wave
awkwardly if you are super shy…)
Identify AS MANY TRAITS AS POSSIBLE in 4 minutes.

10. Voting On Our Classroom Pet
 What kind of pet are we going with? Let’s decide.

11. Trait Similarities
Notice that among related animals, general traits are similar.
(i.e. all of the Elephant varieties had 4 legs, a trunk and tusks)
But what if we COULD genetically alter a pet to produce a new
species with the traits of several species? What would your
ideal designer pet be??

12. Choosing a base pet
Discuss at your table ideas for a base pet. If you have your
phone, scan the QR codes at the front if you didn’t already.
What pet do we want to use as the class pet? Join the
discussion on Backchannel chat. NEW RULES FOR BCC
I’d like to end up with this being our class mascot. Really spend
some time thinking of good ideas for your animal that will
represent the class!

13. Choosing traits
We want to alter 7 traits for our pet.
What are your ideas for traits? Post them to Today’s meet.
A.) Animal size
B.) Body covering (skin? scales? Armor?
C.) Number of arms/legs
D.) Coloration
E.) Number of eyes
F.) Type of tail
G.) Hand/Foot type

14. Pick your traits
Make your choices for YOUR INDIVIDUAL animal.
Draw your perfect pet
Name your perfect pet species
Describe your pet in detail, focusing on:
 traits from the original species that you changed
Why you feel that your traits are more beneficial. What are the
advantages of your pet over the original?

15. Standard?
Develop and use a model to describe why asexual reproduction
results in offspring with identical genetic information and sexual
reproduction results in offspring with genetic variation
So how do we remember this? Lets look at some examples.

16. Try creating your standard to share
5 minutes

17. Exit Slip Reflection:
Take a look at your picture.
What are the possible problems or disadvantages of owning
this pet in reality? Be specific.
