Question 1
Upload your required lab photograph of your pedigree drawing here. Reminder: The system does not let you upload more than one file in response a single “question.” If you try to upload a new picture, your previous photo will be REPLACED with the new upload.
LAB 13 ONLY REQUIRED PHOTO: photo of your pedigree drawing that matches the background information provided to you about George and Vanessa’s family and their history of cystic fibrosis. I strongly recommend labeling each individual with the genotype you think they have (based on the background information and how cystic fibrosis is inherited) for all individuals whose genotype you know for sure. Leave the ones that are unclear blank or write a ? to indicate you aren’t sure.

Question 2
How is cystic fibrosis inherited? Chose:
• Autosomal dominant
• autosomal recessive
• sex-linked dominant
• sex-linked recessive
Question 3
Based on the background information and your pedigree, what is the genotype of George’s mother?
• homozygous dominant,
• homozygous recessive,
• heterozygous

Question 4
Based on the background information and your pedigree, what is the genotype of George’s father?
• homozygous dominant,
• homozygous recessive,
• heterozygous

Question 5
Explain how you determined the genotypes you selected in questions 3 and 4 about George’s parents.

Question 6
Based on the background information and your pedigree, what are the possible genotypes for Vanessa? Select ALL the genotypes that are reasonable for Vanessa to have inherited.
• homozygous dominant,
• homozygous recessive,
• heterozygous

Question 7
Based on the background information and your pedigree, what are the possible genotypes for George? Select ALL the genotypes that are reasonable for George to have inherited.
• homozygous dominant,
• homozygous recessive,
• heterozygous

Question 8
Explain how you determined the genotypes you selected in questions 6 and 7 about Vanessa and George. Write your answers in paragraphs here: ———————————————-

Question 9
If Vanessa and George have children, what possible genotypes and phenotypes, could their children inherit? If more than one possibility exists, describe BOTH the BEST and WORST case scenarios.

Question 10
If Vanessa and George wanted to be sure they knew whether their child would be sick with cystic fibrosis before their child was born, what prenatal testing options did you learn about in Chapter 11 that could help this couple? How and when would these tests be performed?
All answers in full. ——————————————
Question 11
The online lab explains how PCR works and how some of the DNA technologies you learned about help scientists investigate crime scenes.
(Part A) Using what you learned in Chapter 11 and in these lab videos, describe why the PCR procedure is able to make so many copies of a small sample of DNA in just a few hours.
(Part B) Other than crime scene analysis, describe another situation where scientists can us PCR to help them save lives. Make sure to describe both the situation AND how PCR would help with this.

Reminder: Do NOT copy and paste information from any websites, explain it using different words! I want to know what YOU think about it, not how the website wrote it!

Question 12
How is PCR similar to the DNA replication process that occurs prior to mitosis? How is it different? In your answer, describe at least three ways they are similar and at least three ways they are different.
