/in /by

Instructions

The questions on this lab quiz are based on “Module 2: Phylogeny”  of the MMHI Lizard Evolution Virtual Lab. You may open the virtual lab,  which will open in a separate tab, at the same time as you take the lab  quiz. There is a 90 minute time limit. You may take the quiz two times,  with your higher score counting towards your grade.

Complete the virtual lab module: “Module 2: Phylogeny” of the HHMI Lizard Evolution Virtual Lab at https://www.biointeractive.org/classroom-resources/lizard-evolution-virtual-lab   Note:  At this site, click on “Launch Interactives” and then run Module  2 (just Module 2; you don’t need to run any of the other other  modules).  The lab takes about 45 minutes. Lizard Evolution Virtual Lab instructions

Assignment: SCIE207 Phase 3 Lab Report

Title: Lab to Determine the Outcome of Heredity

Instructions: You will fill out the Punnett squares and answer a set of questions for each exercise.

When your lab report is complete, submit this document to your instructor in your assignment box.

Using what you learned on the lab animation (and the images below), you will fill in the following Punnett squares and answer the questions that follow:

Exercise 1: Color Blindness

A. Choose the parental gametes, and align these in the correct positions around the Punnett square. (Type in the correct gametes. Pink are the female gametes, and blue are the male gametes. XC is the gene for normal vision, and Xc is the gene for color blindness.)

 

C

B. Choose the correct genotype of the progeny to fill in the Punnett square.

(Type the correct genotypes in the boxes.)

 

______ ______

 

______

 

______

Question Answer
What is the genotype of the mother?  
What is the genotype of the father?  
What are the possible phenotypes of their children?  
What is the probability of the color blind trait in female children and the probability of the color blind trait in male children?  
X and Y genes code for male and female gender. XX is female and XY is male. Why is XcY color blind, but XcXC not color blind? Can an XcXC female pass the color blind trait to her children?  

Exercise 2: Freckles

C. Choose the parental gametes and align these in the correct positions around the Punnett square. (Type in the correct gametes. The pink are female gametes, and the blue are male gametes.)

 

A. Choose the correct genotype of the progeny to fill in the Punnett square.

(Type in the genotypes.)

 

______ ______

 

 

______

 

 

______

Question Answer
What is the genotype of the mother?  
What is the genotype of the father?  
What are the possible phenotypes of the children?  
What is the probability of freckles in their children?  
Freckles in humans are inherited by which pattern: dominant/recessive, incomplete dominance, or codominance? Why does the mother have freckles, even though she has a gene for no freckles? Why does the father have no freckles?  

Exercise 3: Blood Type

A male has Type A blood, and a female has Type B blood. Could they have a child with Type O blood? Demonstrate how this is genetically possible by filling out the Punnett square.

Choose the correct parental gametes from all of the potential blood type gametes below, and align these in the correct positions around the Punnett square. (Type in the correct gametes. The pink are female gametes, and the blue are male gametes.)

 

A. Choose the correct genotypes of the progeny, and fill in the Punnett square.

(Type the correct genotypes into the boxes from the possible genotypes shown below).

______

 

 

______

Question Answer
What is the genotype of the mother?  
What is the genotype of the father?  
What are possible phenotypes of their children?  
What is the probability of Type AB blood in their children?  
Ms. Johnson is suing her former husband for potential child support payments for her 2-year-old child. Mr. Johnson’s attorney forcefully denies the fatherhood of his client, stating that the child of Ms. Johnson has blood type O, while the blood type of Mr. Johnson has Type A blood. The lawyer claims that Mr. Johnson cannot be the father of a child with Type O blood. Is the attorney right? Why or why not? Explain your answer.

The global community

/in /by

The global community is plagued by increasing incidence of leukemia; non-Hodgkin lymphoma; lung, colorectal, breast, pancreatic, prostate, liver, ovarian, and esophageal cancers. Other types of cancer exist but are less frequent. What is the scientific community doing to attempt to eliminate the most common forms of cancer that are ravaging society?

1. Read the course textbook’s chapter on cell division, specifically the last section on how cells become cancerous. This is context for completing Individual Assignment 3.

2. Watch the Presentation in Module/Week 9 entitled “Ways to Fight Cancer.” Notice that the presentation outlines essentially 3 approaches to fighting cancer: a) reduction of cancer risks, b) correction of cancer genes, and c) destruction of cancerous tissue.

3. Open the “10 Discoveries in the War on Cancer” document in the Assignment Instructions folder. Scan the discoveries briefly. Then, open the assignment submission link in Module/Week 9. In the text box, number from 1 to 10 for the 10 discoveries.

4. Reflect carefully on discovery 1. Would this discovery be more useful for a) reducing cancer risks, b) correcting/restoring cancer cells to normal, or c) destroying cancerous tissue? After number 1 in your list, place in parentheses the letter representing the approach to fighting cancer that will best be served by this new discovery. (More than 1 approach may be served, but which is most likely to be helped most significantly?)

5. Repeat this analysis for each of the remaining 9 discoveries. Return to the “Ways to Fight Cancer” presentation as needed for additional perspective. When finished, your entire text box must be simple: a numbered (1-10) list of letters (a), (b) or (c). The assignment is now complete.

6. Each correct association up to 8 correct answers is granted 7 points. If you get 9 or 10 out of 10, you get a perfect score (60 pts.) on the assignment.

Submit this assignment by 11:59 p.m. (ET) on Monday of Module/Week 9.
