I. Rules of inheritance (of genes)

a. are inferred from PATTERNS of gene

transmission from one generation to the next

b. are used, once known,to study nature and function of genes

to deduce individual genes properties

to predict offspring types

II. Biochemical study of gene function gives more

precise understanding of gene action.

BioS 220

An i>clicker remote isrequired for this course.

You can purchase it

through the bookstore.


28/34

How will we

use the clicker? I pose questions on the screen during

lecture.

You answer using your i>clicker remote.

Class results are tallied.

I display a graph with the class resultson the screen.

We discuss the questions and answers.

You get 1 point for participating and 4for answering correctly)!


29/34

How do you vote?

Turn on the clicker by

pressing the bottom On/Off button.

A blue Power light will

appear at the top of the

remote.


30/34

How do you vote?

When I ask a question in

class (and start thetimer), select A, B, C, D,or E as your vote.


31/34

How do you know your

vote was received?Check your Vote Status Light:

Green light = your vote was sent

AND received.Red flashing light = you need to vote

again.

Not sure you saw the light? Just

vote again.

Want to change your vote? You can

vote again as long as the timer is stillgoing.


32/34

Registering your i>clicker

You can earn points for your i>clickerresponses [for participation and/oranswering questions correctly].

Until you register your i>clicker, yourresponses are tied to your clicker remote ID

(located on the back of your clicker), ratherthan to you.

When you do register, your previously

recorded voting responses will be assignedto you.


33/34

Registeringyour i>clicker unit

1. Go to BlackBoard.2. Go to Bio 220.3. Under Tools:4. Enter your iClicker

serial number.


34/34

Other tips If you bought a used clicker, replace the batteries.

Register your clicker by January 21.

Before using a new clicker for the first t ime, pull the

plastic tab out of the battery compartment.

Bring your clicker to class every day!

Make sure your remote is on when voting!
