1. Describe the phenotypes and genotypes of the parents that you chose on the Punnett squares screen.

2. Describe the offspring phenotype and genotype ratios that resulted from crossing the parents that you chose on the Punnett squares screen. Using these ratios, what percentage of offspring is white-eyed? What percentage of offspring is red-eyed?

3. Did you mate Drosophila in the laboratory or did you perform genetic crosses using Punnett squares first? Why? Compare and contrast the data you collected from the Punnett squares to the data you collected from the Drosophila mating.

4. In a mating between a red-eyed male fruit fly and a red-eyed heterozygous female, what percentage of the female offspring is expected to be carriers? How did you determine the percentage?

5. In a mating between a red-eyed male fruit fly and a white-eyed female fruit fly, what percentage of the male offspring will have white eyes? Describe how you determined the percentage.

6. Hemophilia, a blood disorder in humans, results from a sex-linked recessive allele. Suppose that a daughter of a mother without the allele and a father with the allele marries a man with hemophilia. What is the probability that the daughter's children will develop the disease? Describe how you determined the probability.

7. Colorblindness results from a sex-linked recessive allele. Determine the genotypes of the offspring that result from a cross between a color-blind male and a homozygous female who has normal vision. Describe how you determined the genotypes of the offspring.

8. Explain why sex-linked traits appear more often in males than in females.

  4. Exercises and notes are due first thing when you walk into the room on Tuesday. Your work must either be handwritten, or if you typed it you must PRINT BEFORE CLASS. I will also check that you took quality notes and give you a grade for that as well.
  5. If you have questions about how to take notes please see me as this is an important skill.
    1. In order to take the notes, follow the assessment statements and make sure you've done all the things they asked.
      1. For example: Assessment statement 2.3.4 states that you must compare prokaryotic and eukaryotic cells, therefore, your notes should have a section for that.

Dear 11th grade,
My internet has been out since Friday. I apologize for not getting your feedback to you. I just got my connection back and I'm working on finishing up. I'll get it to you by morning. Let's change the deadline to next THURSDAY (31/10) at midnight (after the clock strikes Friday, it's late).
Thanks,
Miss Kellie

Take the quiz to review

Homework: I will check your notes tomorrow. You will have to answer a few questions correctly in class in order to be able to begin your lab.

Sept 26:

Warmup:
Looking at your homework:
  • What did you notice about the total number of cubes and the volume of each each figure?
    • How does this help you to define volume and the units used to measure it?
  • What did you notice about the total SA of all the individual cubes that make up a figure, as compared to the SA of the figure itself?
    • How can you explain this difference?

Today we:

  • Checked the homework
  • Finished discussing SA:V
  • Introduced the concept of emergent properties and stem cells


Homework: Study for QUIZ on Tuesday
  • Review:
    • Stats (averages, standard deviation, t-test, causation/correlation, etc.) -- use your practice IB test to review
    • Characteristics of living things
    • Cell theory
    • relative sizes of molecules, cell membrane thickness, viruses, bacteria, organelles and cells, using the appropriate SI unit.
    • calculating the magnification of microscope images and scale drawings.
    • SA : V ratios
    • The fundamental idea behind emergent properties

Sept 25:

Warmup: A student views an image of a cell magnified 350 times. The image is 250 mm long. What is the actual length of the sample in the image in micrometers? (If you're stuck, draw it out!)

Today we:
  • Reviewed magnification calculations
  • Discussed volume and SA
  • Introduced the concept of SA to Vol ratio and described how that relates to cell size.
    • This ratio helps us describe why cells are small.

Homework: Review sheet: Why are cells small?

Sept 24:

Warmup:
Define volume (V)
Define surface area (SA)
Describe how to calculate each

Today we:
  • Calculated the magnification of microscope images and scale drawings

Notes from today (Thanks, Camila!):
