completed, save the LAB_WORK SHEET with your last name & submit within Work2Do tab. Be sure to save your

document as LASTNAME_lab7. My last name is Ashraf, so my file would be named Ashraf_lab7.

Directions

This lab is an on‐line lab. Read the text below and answer the questions

within each part in a word processor document. Mendelian Genetics

Gregor Mendel was a biologist now known as the "Father of genetics,"

(both because he was a monk and because he was the ﬁrst to

quantitatively determine how various genetic traits were passed on from

parents to offspring). Although he could not have known about DNA and

genes at the time, his conclusions about a number of crossbreeding

studies he carried out (as described in chapter 10 of your textbook) were

vital to the development of genetics. Some years after Mendel, Dr.

Reginald Crundall Punnett developed a graphical tool, the Punnett square,

for predicting the genotypes of offspring from cross‐breeding

experiments involving genes that operated like those Mendel studied.

Part 1: Complete the following brief exercise to familiarize yourself with Punnett squares. Follow the link and read the

University of Arizona's Biology Project's tutorial on how to set up a Punnett square:

B. Answer Questions 1 & 2 on the lab write‐up worksheet (write answers there—not here!) after you have

completed the tutorial to test your understanding.

Part 2: Blood Typing human blood (types A, B, AB, and O) is an example of a trait that (mainly) works according to

Mendelian genetics. For instance, there are dominant traits (A and B) and a recessive trait (O) that are the result

of speciﬁc alleles (note: the A and B alleles are co‐dominant so that, when paired, they produce type AB blood).

Additionally, there is another component to blood typing—the Rh factor—that comes into play, producing

‐

positive and negative blood (e.g. A

, B

, etc.). The following tutorials will assist you in learning about how blood

types arise and how to determine them using antibodies. Once you have mastered the genetics behind blood

types, you can test your skills on cyber‐patients who have recently been in a car crash and need blood!

Go to University of Arizona's Biology Project tutorial on blood types and read the "Introduction" page:

B. Click of the words "Human ABO markers" on the left side of the screen. Read about the ABO markers.

C. Next, click on "Blood types and genotypes?" on the left side of the screen. Read about how blood type

genotypes result in different blood type phenotypes.

D. Click on the new “Blood type and Rh Factor calculator” on the left side of the screen and determine both the

possible blood type of the child and the possible blood type of the parents.

E. Click on the words "Rh factor" on the left side of the screen. Read about the Rh factor and how it inﬂuences

blood types.

F. Answer Questions 3, 4, 5, 6, 7, 8 on your worksheet (not here!)

Part 3: Now, let's test your blood typing skills! Go to the following web site located in the Nobel e‐Museum (from the

Nobel foundation ‐ as in "Nobel prize" ‐ in Sweden):
