Today we took a SWYK to demonstrate our understanding of genetics and heredity thus far.
We also read from the textbook pages 117-121 to discover how genetics disorders occur: DNA mutation perhaps? dominant or recessive trait inherited? maybe something went awry during meiosis and we have too many or too few (or even broken) chromosomes? or maybe some environmental factor caused a change to occur!
We used the Gene Screen app to explore more about genetic disorders. You can also explore disorders AND MORE on the Learn Genetics website. Click and EXPLORE!!!
IF YOU MISSED CLASS TODAY you will need to read about genetic disorders and possibly choose to explore the LEARN GENETICS SITE. You also have a SWYK to make up!!!
Next week is all about the cool advancements in genetics! We also have our SBAC testing!
Today we turned in our Venn diagrams, added WALTER SUTTON and NETTIE STEVENS to our GOSATOT, and modeled the phases of meiosis using Oreos and sprinkles! Tomorrow we shall SWYK on meiosis and Punnetts (this time using X and Y chromosomes). We will also discuss how genetic disorders occur. IF YOU MISSED CLASS TODAY view the models in the slideshow below and be ready to SWYK!
Today we continued with our understanding of meiosis (sex cell formation). We compared and contrasted mitosis with meiosis (yep, a Venn diagram) and explored the connection to Punnett squares yet again. IF YOU MISSED CLASS TODAY you should PRINT THESE NOTES and then complete a Venn diagram on a sheet of loose leaf paper. Be sure to discuss the phases, sequence, events, and purpose of each process. Include cell number from start to finish, what happens to the chromosomes, AND any organelles involved!
Today we began our understanding of how sex cells (egg or sperm) are made AND that connection with Punnett Squares! IF YOU MISSED CLASS TODAY you will want to watch the video below AND read pages 92-96 AND PRINT THESE NOTES for page 124 in your notebook. Tomorrow more with meiosis.
Today we did some coin flipping to determine traits of a child! A little different than making our actual children because we are just using pennies (heads or tails) to determine dominant and recessive alleles. It's not really how it works with egg and sperm and YOUR traits BUT it's fun to draw a kiddo. IF YOU MISSED CLASS TODAY you will need to come in to make your baby! Tomorrow we discuss meiosis!
Today we took a SWYK to demonstrate our understanding of heredity using Punnett squares. We explored traits found with Sponge Bob and others in Bikini Bottom. IF YOU MISSED CLASS TODAY you will need to make up the SWYK upon return. We will explore more about heredity next week AND revisit cell division.
Today we checked our Punnett Practice Page (fun alliteration) AND we explored many different human traits and practiced MORE Punnetts to predict the probability of events occurring! Tomorrow we shall SWYK on our understanding of the terms of heredity and genetics as well as using Punnett squares to predict probability of genetic crosses. IF YOU MISSED CLASS TODAY make sure you read pages 110-116 of your textbook and watch THIS VIDEO ABOUT NON-MENDELIAN GENETIC CROSSES and be ready for the SWYK tomorrow! We added the terms X-chromosome, Y-chromosome, sex linked gene, and carrier to our glossary as well! Remember your notebook glossary is the ONLY help you can use on the SWYK... have terms defined!
Today we began our practice of Punnett Squares. IF YOU MISSED CLASS TODAY you can print this worksheet and begin OR you can come grab one during study hall tomorrow and work. Some of us are catching on to this Punnett's business pretty easily and some of us aren't quite there YET... keep trying! There is a cool Punnett calculator to use ON THIS WEBSITE. You can use it to help complete your worksheet or check your worksheet when done or just see how to calculate probability with Punnett squares!
I am guessing pretty low percentage of you are fully up to date with all the highlighted terms (we added a few more today as well: phenotype, genotype, homozygous, heterozygous, codominant, and Punnett square). Tonight would be a great night to have all vocab terms caught up for quick reference! IF YOU MISSED CLASS TODAY you will want to read pages 84-89 of the textbook, watch the video below about Mendel and his peas (and Punnett squares), and PRINT THESE NOTES. Tomorrow we have Punnett Practice!
Welcome back from break (to most of you)! Today we spent a bit of time remembering genes and DNA. Our lab activity involved selecting genes for the traits of a dog and then we drew a picture of the dog! A good opportunity to understand genotypes and phenotypes as well as explore genetics in other organisms (DOGS). IF YOU MISSED CLASS TODAY you are welcome to make up this activity during study hall, lunch, or after school when you return. Tonight would be a good night to add terms to your glossary!
