-­‐-­‐ J If printing, print double sided to save the trees J -­‐-­‐ Intro (15min): Review kahoots from last week. Activity #1 (20min): Human genetics, karyotyping and chromosomal mutations –
define terms. Everyone will divide up into pairs. Each pair is assigned terms to define. Each pair will teach their terms to the rest of the group. To define: Abnormal karyotypes and diseases 12.Duplication. 1. Euploid vs. Aneuploid. 13.Reciprocal translocation. Give an example! 2. Trisomy. Give an example. 3. Nondisjunction. In what phases of meiosis does it occur and how? Human genetics 14.A pedigree. Draw one! 4. Klinefelter syndrome. 15.Wild type. 5. Turner syndrome. 16.Incomplete dominance. Give an example! 6. Polyploidy. 7. Triploidy. 8. Autosome. 9. Sex Chromosome. Chromosome structural changes 10.Deletion. 11.Inversion. 17.Codominance. Give an example! 18.Multiple alleles. 19.Carrier. 20.*Epistasis. 21.*Polygenic inheritance. 22.*Pleiotropy Activity #2 (40min): Complete dihybrid cross mini-­‐worksheet, then kahoots quiz. • Dihybrid cross: you are crossing two F1 generation pea plants and are tracking two different traits: flower colour and flower shape. There are two colours, blue (dominant) and orange (recessive), which you represent by C and c respectively. There are two flower shapes, star shaped (dominant) and moon shaped (recessive), which you represent by S and s respectively. Note that the P generation crossed a “father” plant phenotypically recessive in both traits with a “mother” plant that was true-­‐breeding with regards to the dominant alleles of both traits. Complete the punnett square, representing your cross, below. Then complete the following 3 fill in the blank sentences. 1. This square represents the __________ that a _______ offspring will represent a particular trait. 2. If flower shape was an __________ trait then the _________ that a single offspring would exhibit flowers half-­‐way between star and moon shaped would be ___%. 3. In the 9:3:3:1 dihybrid cross ratio, the phenotype represented by 9/16ths is ______, ______-­‐shaped flowers. Those represented by 3/16ths are ______, ______-­‐shaped flowers and _______, ______-­‐shaped flowers. Finally, the phenotype that a single offspring shows 1/16th of the time is _______, ______-­‐shaped flowers. • Now we’re doing kahoots!! Closing (5min): • Thursday group: goodbye! • Monday group: Choose next week’s activities!!! Think about what areas you need to put extra work into and choose three from the list below (numbers). Think about what activities you might like to use to review your chosen concepts; choose three activities (letters). 1. Human genetics. 2. Mendelian genetics and inheritance. 3. Karyotypes and chromosomal mutations. 4. Mechanisms of genetic diversity in prokaryotes (transformation, transduction, conjugation). 5. Operons and regulation of prokaryotic gene expression. 6. Regulation of eukaryotic gene expression. 7. DNA replication. 8. Transcription. 9. Translation. 10. Something else: [write it down]. A) Kahoots. E) Chalkboard writing (like today). B) Fill-­‐in-­‐the-­‐blanks. F) Diagram drawing on chalkboard. C) Mini mult. choice quiz. G) Define key terms. D) Divide material into parts. Assign one part to each group. Group reviews material, then presents to others. H) Headbands. Happy Studies J -­‐-­‐Zeke I) Some other activity: [Write it down].
