genotype - genes of an individual for a particular trait or traits.
phenotype - Visiable expression of a genotype. This was the noticable change in the color of the dragons when you change different genes.
allele - Alternative form of a gene, occur at the same cous on homologous chromosomes.
dominant allele - Allele that exerts it phenotypic effect in the heterozygot, masks all the expression of the recessive allele.
recessive allele - Allele that exerts in phenotypic effect only the homozygote, its expression is masked by a dominant allele. The fly will not change its color if the color is a recessive allele.

SELF/UNIT EVAL.
Lacey, thanks for the very honest and thoughtful self-eval. I agree, cancer is amazing to understand and makes sense once you appreciate the biology, although certainly it’s repercussions can be so terrible and unfair. Please, on all the assignments, be sure you read the directions carefully because, for the unit eval, I would have liked to get your feedback on the questions that I have posted…for next time!
COMPENDIUM REVIEW 1: CELLS
This is an interesting approach to the compendium. I appreciate your posting links to the images…it seems a good and easy way to go. For some reason, some of your links are “live”…I just have to click on them and they open. Others just have the URL address and I had to copy and paste them into a new browser window. I think it probably depends of you have a line return after you paste the image into your blog posting. I would encourage you next time to organize things a bit more…try creating topics and then doing your quick bullet-point sentences below each topic…maybe separating them with little bullets or dashes.
COMPENDIUM REVIEW 2: GENETICS
I didn’t see a second review for our second topic on Genetics…there were some points about genetics in your cells topic review, so I have awarded some points here, but be sure you do two separate compendium reviews, one for each topic in the unit.
MICROSCOPE LAB
Your image is perfect as are the descriptions of the parts of a microscope. The instructions also ask for some background and history on the microscope to make it an exemplary write-up.
DRAGON GENETICS
Your images are exactly right and so I know you did the lab. Just be sure you read the write-up directions to include all of what you should. I accept the images as a baseline indication that you’ve done it, but would like the additional write-up information to be sure you understood the significance of the images.
BUILD A CELL
Boy, I that a great-looking cake. Too bad being sick kept from enjoying it—should have frozen it for later! I think this is a nice baseline look at how a cell is put together and you do represent and label everything well. The instructions also ask for an indication of how DNA replicates, how cells divide and how proteins are formed…probably would have taken another cake…or some chocolates on the side!
ETHICAL ISSUE ESSAY: GENETIC ENGINEERING
I think you do a great job in this essay of seeing many different sides of the issue and finally coming down on looking at how it might be used and that being perhaps the most important point, regardless of all the other social/ethical issues that come into play.
Lacey,
Please don’t forget to do your peer color group feedback on their ethical issues essays—you’ll probably find it interesting to see some other blogs also. And get started on Unit II if you haven’t already. Let me know if you have any questions or concerns about this feedback or your grades which can be seen on the YC Blackboard site.
Thanks for all your hard work on this unit. In your own self-eval, you saw how a bit more planning and time would have resulted with more complete assignments. I do encourage to be sure you read exactly what the instructions say and be sure all of that is in your assignment. For example, on the online labs, be sure your write-up has all the pieces that are there…it’s just a bit more work to go from basic to exemplary (that is form a C to an A). Also, be sure you do two compendiums for each of the two topics in each unit of the course. I really liked your cell and I’m sure I would have enjoyed eating it, even if you were to sick…oh, well. And your essay was very insightful. Keep up the good work and I think you’ll find the next unit a bit less burdensome in terms of new information,
LF
