Biology Questions Chapter 4 (Larry Cheeks)

16. If you were Mollie, would you have the test to determine if you were a carrier for cystic fibrosis? 
-Yes, I would like to take the test because I would not like to pass it down to my child.

17. What are the symptoms of the disease? 

-Symptoms vary and can include cough, repeated lung infections, inability to gain weight, and fatty stools.

18. How can reproductive technology increase a couple's chances of having a healthy child? 

-One form of reproductive technology is artificial insemination. This is where a sample of sperm is taken from a man, cleaned in a special way, and then injected into his partner’s uterus. If the male in a couple carries a mutated gene causing a dominant disorder, the couple may choose artificial insemination using sperm given by a donor.

19. If Mollie is tested and found to be a carrier for the disease, do you think the couple should still try to have a child? Why or why not? 

-That means his children will have the disease only if they inherit the mutated gene from both parents.

20. If the couple conceives, and a genetic test confirms that the fetus will have the disease, should the pregnancy be terminated? Explain your reasons. 

-Yes, because the baby will eventually have the disease.

21. How can ex utero genetic testing help Carlos and Mollie have a healthy child? 

-The testing is done after eggs and sperm have been mixed together using in fertilization.

22. It is possible that in the future, genetic testing on a fetus could be done to determine other traits, like eye color, intelligence, or even probability of obesity or alcoholism. What do you think about this? Would you have your baby tested before it was born? Why or Why not? 

- Yes, I would have my baby tested before it was born to notify me if my baby have the disease or not.  

23. (Vocabulary) What is a DNA Marker?

- is a term used to refer to a specific DNA variation between individuals that has been found to be associated with a certain characteristic (e.g., increased tenderness).
