1. Turn in your homework hot Topics in Genetics What is Genetics you may ask?The study of how traits are passed along. Brainstorm with the student next to you to come up with a list of interesting topics that are related to genetics or DNA. Write that list on both your RPs. Who will have the best list?

3. RP: on your old RP . . Answer this question: It was gorgeous this weekend, tell what you did outside (please say you went outside) that was exercise. Then tell why exercise is good for your circulatory system.

4. Today in Science ! Introduction to Genetics Two column Notes Notebooks . . . • They will be turned in Monday. • Be sure to do fill in your “student evaluation” on your rubric. • The Peer evaluation can be done first thing on Monday. Lizards and pythons and newts, oh no!

5. Notes – NB# 4 of new notebook • Write the topic in the left, listen to lecture then write one sentence summarizing what you thought was interesting. • There will be some questions to answer also. • There are about 6 hot topics that we will discuss. These are HOT topics. I picked them because they are engaging. AND yes, you will get to talk to each other about each topic . . .but please wait ‘till it is your turn.

6. Hot topicsA. Genetic Disorders • Progeria is a genetic disorder caused by a mutation in the DNA that has occurred in 1 in 4 million children.

25. In Summary . . . Write one question you still have. Write a one sentence summary of how selective breeding works.

26. C. Genetic Modification • Changing the DNA of an organism by Scientifically inserting DNA segments into the chromosomes.

27. Controversial Selective Breedingdesigner babieslittle persondeaf person Add this question and your opinion to your notes: Should parents be able to “design” a baby that has the same disability as they have?

28. Speaking of controversy …how about cloning? On your Notes write and anwer this: I think that cloning is ____________________

29. What is cloning? D. Cloning is making an exact copy What do you already know about clones? Any asexual reproduction process results in a “clone” cause DNA is identical. Examples: budding, binary fission, rooting

30. a.k.a.Somatic cell nuclear transfer . . . • Dolly the sheep is most famous clone. • There were 277 attempts before it worked. • 1 cell from sheep A mammary gland with the nucleus (and DNA) removed. • This nucleus was put into an unfertilized egg cell from another sheep. • This cell was then inserted into a surrogate sheep. • Dolly died prematurely.

31. Dolly’s life Life span for a sheep is generally 12 years. At 5 she developed arthritis and then lung disease. Dolly “died” when she was 6. Dolly had at least 4 of her own lambs.

32. E. Stem Cell Research • Stem cells are those early cells that have not differentiated (become a bone, skin whatever cell).

33. GPS for our study of Genetics • S7L3 Students will recognize how biological traits are passed on to successive generations. • S7L3a Students will explain the role of genes and chromosomes in the process of inheriting a specific trait. • S7L3c Students will recognize that selective breeding can produce plants and animals with desired traits.

37. Rules: Keep your voices down – you do not want other groups to hear your definitions. Figure out ways to convince them that your made up definition is the right one. We will not give the correct answer till the end. One definition can be funny, but we’ll know not to pick it probably. Your made up defs.can not be correct.
