...used? Students should also answer each of the following questions: 1. How did you determine which chromosome (with its associated gene) each parent would contribute to the child? 2. If each coin represents a homologous pair of chromosomes, how does the flip represent the behavior of chromosomes in meiosis? 3. What is the difference between experimental and theoretical probability relative to this lab? How are these two concepts related (tied to this lab)? 4. Using an example from this activity, explain your understanding of the words genotype and phenotype 5. What is the experimental probability that both r...

...lights will be: a. the first significant rise in atmospheric oxygen (about 2 billion years ago, to the 2% level), you could have an oxygen molecule model here. b. the first sign of sexual reproduction ("...the beginning of SEX!" [in the form of 1 billion year old fossils of cell tetrads, suggesting meiosis]) c. the pre-cambrian appearance of multicellular organisms (algae and wormy animals, 600 mya to 545 mya) d. the cambrian "explosion" of diversity of invertebrates (545 mya) e. the first fishes (~500 mya) f. the first amphibians (~360 mya) g. the first reptiles (~300 mya) h. the first mammal-like reptiles,...

...e window as possible for best results. The fifth experiment consisted of taking our plants out of the bag and dissecting the root of one of them. We observed the root under a microscope to see if we could detect the kind of cell growth that had caused the plant to grow. What we were looking for was meiosis to take place, that's when cells divide to make more cells. They undergo ordinary cell division to produce multicellular, haploid organisms. Certain cells of these haploid organisms later become gametes, and fuse to form a zygote. As you may know, in both plants and animals one of each pair of chromosomes...

  34.   Cell Division and Mitosis
...students can observe that different organisms have cells which look very similar. Different races and nationalities of people must have cells which are not distinguishable from each other. 2. It may not be necessary to use a visible pipe cleaner model to better understand mitosis, but when teaching meiosis the model is very good to demonstrate crossing over and variable gamete formation as well as differences from mitosis.

Make a key for the traits for a garden pea plant, and give one to each student. Make a transparency diagramming meiosis using letters in lieu of sex cells. Make another transparency of a Punnet Square, diagramming the cross of the F1 gametes from the first transparency. Have a vocabulary sheet with the following information and definitions: Gregor Mendel, dominant character, recessive character, alleles, homozyous, heterozy...

Include a photodiary for your experiment q Choreograph and teach a meiosis dance q Research how cloning has been portrayed in the movies (e.g. Multiplicity, Gattaca, The Island). Are they being fair and accurate? q Write a report (include diagrams) comparing the embryonic development of two species q Compare and contrast the three kinds of microscopes studied using a Venn diagram...
