  1. Autozome X vs Y Bully Alleles What’s in your jeans? Do you need Therapy? 100 100 100 100 100 200 200 200 200 200 300 300 300 300 300 400 400 400 400 400 500 500 500 500 500

  2. 100These only are expressed in the homozygous form.

  3. What is a recessive allele?

  4. 200What is an example of epistasis in humans?

  5. What is a albinism?

  6. 300 What is PKU?

  7. PhenylketonuriaThis causes mental retardation due to a build of proteins.

  8. 400 What is cystic fibrosis? What is the cause? What kind of gene is this?

  9. Excess mucus is made in the lungs, digestive system, liver, etc. The protein channel to remove chlorine is incorrect. It shows peleiotropy.

  10. 500 What is Ellis-van Creveld Syndrome?

  11. It causes polydactylism and dwarfism. It is recessive and an example of founder’s effect.

  12. 100Who determines the sex of a child? Explain.

  13. The male determines the sex. He carries the X and Y chromosome.

  14. 200What is hemophilia? Who has it more? Why?

  15. Hemophilia is the bleeder’s disease caused by a missing AHF protein. Men have it more. It is carried on the X chromosome.

  16. 300What is this called? What disorder does it show?Is it a male or female?

  17. What is a karyotype? It shows a woman’s chromosomes with Turner’s syndrome.

  18. 400What is trisomy 21? What is another name for it? What problems do people with this disorder have?

  19. People with trisomy have three #21 chromosomes. It is also called Down’s Syndrome. Problems include mental disabilities, short stature, organ problems.

  20. 500Describe why barr bodies form. Who has them? How does this effect cat fur color?

  21. Barr Bodies form from an inactivated X chromosome. One X in every female body cell is turned off. Calico cats are always female because of this. Different folicle cells have a different X turned off.

  22. 100When are dominant allele disorders expressed?

  23. They are expressed in both the heterozygous and homozygous dominant form.

  24. 200Discuss Huntington’s disease. Tell the symptoms, treatment and cause.

  25. Huntington’s is caused by CAG repeats. The nervous system breaks down over time and death occurs. There is no successful treatment.

  26. 300Name and describe the three genotypes for red blood cell formation. Which one expresses a disease?

  27. NN, NS, SSnormal, codominant, sickle Sickle cell has diseased RBC

  28. 400Describe the relationship between Malaria and sickle cell? Why does this occur?

  29. People with the heterozygous form of sickle cell are somewhat resistant to malaria. The parasite has trouble infecting the RBC which are sickle shaped. It is a genetic anti-malarial disease.

  30. 500 Do a punnett square on the board showing how two people with Achondroplasia can have “normal” children. Explain your results and tell what this disease is.

  31. A a A= disordera= normal A a

  32. 100How are karyotypes made?

  33. Cells are “frozen” in prophase one of mitosis and a photograph is taken of the chromosomes. The chromosomes are magnified and cut out and arranged with their homologue according to size.

  34. 200What is the difference between autosome and sex chromosomes? How many do people have of each?

  35. Autosomes are non-sex chromosomes. Human have 44 autosomes and 2 sex chromosomes.

  36. 300A woman with type O blood marries a man with type AB blood type. Show a punnett square with possible blood types for their children. What antibodies and antigens do they each have?

  37. 0= ii no antigen antibodies A and BAB= IAIB antigen A and B no antibodiesChildren type and A and B only.

  38. 400What is the difference between continuous variation and discontinuous variation? Give one example of each.

  39. Discontinuous- two categories for dominant and recessive phenotypes(pea plant height)Continuous variation- many genes are responsible for variation in phenotypes(human height)

  40. 500What can happen to a mother is a + RH baby is carried by a –RH mother?

  41. Nothing will happen with the first pregnancy. The mother’s antibodies can attack the 2nd baby causing severe problems or death for the baby. A shot is given after the first pregnancy to inhibit antibody production in the negative mother.

  42. 100What is a DNA fingerprint?

  43. It is the “mapping” of your DNA repeats unique to you.

  44. 200What did the Human genome project do?

  45. It sequenced all human DNA. We know the order of all the bases.

  46. 300Describe the steps in gene therapy.

  47. The gene and DNA sequence that causes the disease is identified. The correct DNA is produced or found. A correct sequence of DNA is put into the organism using a virus vector.

  48. 400What is electrophoresis? Describe in detail what happens and how it is used.

  49. Electrophoresis separates DNA according to lengths. Shorter DNA segments move farther through the gel due to - electrical charge. It can be used in paternity tests, identification, crime scene analysis.

  50. 500 How is allele testing done? Be complete.
