6th Grade Assignment Title Page – Disease and student names Introduction – Write last 2 slides for each student’s disease 5-8 symptoms of the disease Pictures of people with the disease (nice pictures) Treatment of the disease Which chromosome is involved? Number of people who have the disease Conclusion – Write second last 7th Grade Assignment 1st Par – Who discovered? List symptoms What population, nationality, or gender is affected? Spelling Complete Sentences Varied Sentence Structure 2nd Par – How is it treated? What tests are used to diagnose? 3rd Par – What chromosome is this disease found on? What year was the disease identified and how long until it was associated with being a genetically transferred disease? Discuss any other genetic connections you learned about as you investigated this disease. How many people have this disease? Male = XY sex chromosomes Female = XX sex chromosomes Father determines the sex of baby. How? X or Y in the sperm ½ set of chromosomes has only one sex chromosome Alleles – different forms of the same gene Blood types A, B, AB, O Alleles A, B, O Controlled by Chromosome 9 Combinations Blood Blood Blood Blood type A type B type AB type O AO or AA BB or BO AB OO If one parent is blood type A and the other blood type O what are the possible children blood types? If a parent is blood type A and the other parent is blood type B what are the possible blood types of their children? Universal donor? No antigens… Universal receiver of blood? Have all the different antigens already in blood… Alters the shape of the red blood cells A = normal allele for red blood cells S = sickle cell allele for red blood cells AA = normal blood type AS = carrier of sickle cell (1/2 of cells are normal) SS = sickle cell disease Identical twins Same egg and same sperm = same DNA Have to be the same sex (two sisters) .5 % of total population Fraternal twins Different egg and different sperm = diff DNA Same sex or different sex (two brothers or a brother and sister) Traits that are carried on the X chromosome Can mothers pass traits to sons? Can fathers pass traits to sons? Can mothers pass traits to daughters? Can fathers pass traits to daughters? Hemophilia “bleeder’s disease” blood clots abnormally slowly or not at all Ryan White died in 1990 from hemophilia, contracted AIDS from a blood transfusion, which is necessary for hemophiliacs when they bleed from injuries often. Royal family has a history of hemo… page 68 QEII does her line have H… in it today? Hemophilia Colorblindness – can’t distinguish between colors Male patterned baldness Shows the size, number, and shape of all the chromosomes in an organism 47 chromosomes Trisomy 21 - 3 chromosomes in a pair Down Syndrome Amniocentesis – test for down syndrome 1 2 3 4 5 Do you support abortion? Would you abort a Down Syndrome child? Does the state have the right to force a couple to abort an unborn handicap child? Would you want to genetically engineer your child? Should it be helping people who are very sick to kill themselves? Amniocentesis – removal of small amount of fluid from sac that surrounds the baby (baby cells are in the fluid – test done between 16-18 weeks Other tests can be done at 10-12 weeks CVS No cures for genetic disorders WHY? 1982 – doctors tested a drug that was to change the cells of Sickle Cell page 71 1989 – identifies gene responsible for cystic fibrosis and changed the gene in the cell and it became normal??? 1:700 births Most common syndrome 1866 JL Down Flat broad hands Flat bridge of nose Flat space between 1st and 2nd toe Can we detect genetic disorders? Can we cure genetic disorders? What do we do if we can’t cure the disorder? ABORTION TAXPAYERS PAY TO KEEP THESE CHILDREN INSURANCE PRICES ??? SOCIETIES COST ??? IS THIS SCIENCE OR RELIGION OR MORALS? Definition – the rules a society lives by What morals do you live by? Make a list of what rules you live by. Put the things that are good on the right. Put the things that are wrong on the left. Karyotype Incomplete Dominance Multiple Alleles Sex-Linked Traits Pedigree Karyotype - pairing of chromatids Nondisjunction Occurs during meiosis when chromosomes do not separate properly Pedigree shows members of a family Amniocentesis - tests fluid around the baby for genetic disorders Codominant – capital letters for all alleles DNA molecules= basic substances of heredity DNA stores and passes genetic information The discovery of DNA was most important discovery of 20th century 1 2 3 4 5 Name the 4 blood types How many different alleles are there for blood type? Name the two different arrangements of alleles for blood type A Name the most uncommon type of blood Name a blood type that has two different antigens. 6. 7. 8. 9. What do we call a picture that shows all your relatives and who had a specific disorder? What gender are you if you have an XY chromosome? Who is the universal donor for blood? Describe what a sickle cell anemia blood cell looks like? 10. 11. 12. 13. 14. Can a sickle cell father pass the disease on to his son? Name 3 diseases that are sex-linked traits. What does it mean when a trait is a sexlinked trait? Describe what a sickle cell anemia blood cell looks like? What do we call the test that removes fluid from next to the baby and does a karyotype? 1. 2. 3. 4. 5. Read directions Only father flips for gender of baby Record an H or T depending on the flip of the coin Record the genotype from the key Record the phenotype from the key
