Genetics on Tuesday February 1st 2011



Hello Everyone!





On class on Tuesday we continued delving in the secrets of Genetics. The homework for Tuesday was the Bikini Bottoms Genetics which you can find
here. At the beginning of class

Ms. D chose us to write down the exercises we did. Next, we continued on the Bikini Bottoms Genetics and we finished the rest of the problems in class. We received another piece of which can be found
right here. The first six problems were a piece of cake but the following four were rather challenging.






An example of a problem would be:





1. In chimpanzees, straight fingers are dominant to bent fingers. Complete a Punnett square to show the genotypes and phenotypes expected for the following cross: heterozygous straight x homozygous bent (F – dominant; f - recessive)



F f



F FF Ff



f Ff ff





Genotypes: FF, Ff, ff Phenotypes: Straight Fingers, Straight Fingers, Bent Fingers



Percentages: Straight Fingers(75 %), Bent Fingers (25%). Ratio: 3:1



For homework we received another set of problems which cannot be found on moodle. A very helpful video can be found right here! In order to grade me you can look at the grading rubric right here. If you want to look at previous things we did, it is all on MOODLE.



The next scribe isssssss................ REZA!

  1. Hey Cip-
    You explained what we covered in class well and you put in a good example of a genetic question, even though you could have made it more clear and you could have added a Punnett Square or something similar to it, so that if someone was absent they could understand the basic point of a Punnett Square. Or you could have put in the definition, as a reminder. It was a good idea of putting a link to Moodle on, and I think that your video was good as well, except that you should have emphasized it a bit more, (maybe you could have changed the color of the word HERE), because it was hard to notice! The different fonts were also a bit confusing at times, but I think you did a good job on not overdoing the colors. All in all good job! -Iva

  2. Hi Ciprian,
    This is a pretty good post. It has a good example of a genetics problem, it has a nice picture, and good use of color. You could have improved some p[arts, though. I didn't really understand the answer to the sample problem - I think that you could have included it in a Punnett Square, just like Iva said. Your link to Moodle was good, but watch formatting - your paragraphs start at the very left and the next rows start a bit to the right. Other than that, ylu have definitely improved your post from last year! Good job!

  3. Hi Ciprian,
    This is a good post. Your color was really nice and it was a good idea to put a video and picture in. I also liked that you had an example problem from the sheet we got. You could have explained what the picture is. Nice job remembering to put in the date of the class and labels. Your links are hard to find because they are the same color as the text.
    Over all I liked you post! :)

  4. Ciprian - This is an improvement from your first Scribe Post. However, I see a few things you could have improved. I like that you hyperlinked to Moodle, the worksheet and a video about phenotypes. But the links are hard to find due to the color of them. You have two nice pictures, but have no captions with them. I am confused with your discussion about the problems in class. You stated four were difficult and then only explained one of them. Plus, because it is lacking a punnett square it is really hard to understand and read. The thing that was disappointing with this choice of a problem was that you used the wrong genotype for one of the parents based on what you wrote out for the problem. The cross should have been Ff x ff. Please proof your science more next time and maybe include some definitions or a video about the focus. I think you could have been more specific on your labels as well, as the class focused on punnett squares, not genetics in general. I do like the font choice and color, although the spacing makes this post hard to follow at times. Maybe next time preview and have someone else proof your work first before publishing. ~Ms. D.

  5. Hi Cip,
    Nice scribe post. You did a good job explaining what the homework was and on what we worked on in class. I also liked that you added a picture of a punnett square at the beginning of the post, although it would have been better to put a caption under the picture. You could have also included more than one problem. The problem would have been a lot more understandable if you added a punnet square under it. I think that the font has a good size, but sometimes the color gets a bit too bright. Next time also try to be careful not to place a picture on the text.

  6. Hey Cip
    Your scribe post was OK and I know that you are capable of much better work. It also looks like you did not go back and review your work, an example of this is that you had your only picture covering some of the text. Besides that your science was good but you did not go into depth about anything we did in class besides punnett squares. You also did not have a great amount of text and there was not a huge variation of text color either. But besides that you had good spelling and grammar.

  7. Hy Cip!
    I liked your post, because you included everything we did in class and included videos and some pictures that were very helpful. You could have included what genotypes and phenotypes mean. I liked that you gave an example of the problems on the sheet. I think it is a good post.

  8. Hi Ciprian,
    That was a really nice post, I liked the font and color you used and I thought it was nice that you added the pictures. I thought it was really nice that you added the hyperlinks and it was a good idea to make it go directly to the word document instead of moodle for once. I also like that you showed the working of the question, but you could have explained what the question meant in an easier way for the 7th graders because it was hard to understand. It would have been also nice if you had added pictures of the class. It was nice that you changed colors, but you could have added more science and explained what all the Fs and the letters mean. I think that you included nice pictures, but you overlapped a picture. You could have added a bit more detail, but it was also nice and easy to read because it didn't overfill with extra and unneeded information!
    Overall though great post, that really caught the reader's attention!

  9. Hi there, Cip!
    This is a really good post. I liked your font, since it was very legible, and your pictures were nice and helpful. You also had nice colors that stood out to the reader and made your post much more interesting to read. You had a link to moodle, and that is really good. Though, you could have added one or more links that explained what you did in class. You also could have been a bit more thorough when you spoke about the things you did in general. When you said "complete a Punnett square to show the genotypes and phenotypes expected for the following cross: heterozygous straight x homozygous bent (F – dominant; f - recessive)", it was a bit confusing, since I wasn't in class and don't understand what "straight x homozygous" means. It would have been good to put a few more pictures either from the internet, or from your class. I can't read some of the sentence when you say that the next scribe is Reza. You should fix that. You maybe could have had a bit of more excitement when you talked about what you did in class. You didn't add ennecessary information, as Vale said, which I think is good. Overall, good post!

  10. Hey Cip,
    Overall, I think it was good that you didn't waste time or space describing unnecessary things, and only included a short summary of the class before describing punnett squares and how to create them. I also thought your use of the example problem was good, however you could have included more of them.
