PRACTICAL I on LABS 1 & 2
Are you ready for the practical???
Below are some questions to help you decide...
Disclaimer: This is not
an exhaustive list, but some of the items you learned in Labs 1 and 2.
The practical may cover some items from those labs not listed.
- Do you know the four phases of mitosis?
- Can you recognize interphase or mitotic cells of onion or whitefish blastula?
- Can you which phase it is in for mitotic cells of onion or whitefish blastula?
- Can you use the microscope?
- Can you explain mitosis & meiosis with the pipecleaners?
- Do you know what happens to chromosome number in mitosis and meiosis?
- Do you know what a primary spermatocyte is? A spermatid? A polar body?
- What is the difference between cytokinesis and karyokinesis??
- Do you know the difference between cytokinesis in plant and animal cells?
- Do you know what we saw in the starfish embryo sample?
- Given a figure of chromosomes in particular phase of mitosis or meiosis, can you determine which one and in what phase?
- Do you know the information on bulletin board or red 3 fold-display board? chromosome numbers? Timing of mitosis? The liver cells?
- Can you recognize the sperm cells we saw in the bulletin board or red 3 fold-display board? The ovary cells?
- Do you know what the cells at each step of oogenesis or spermatogenesis are called?
- Do you know which cells are haploid vs. diploid in oogenesis & spermatogenesis?
- Given N, do you know how many chromosomes are in a haploid cell? a diploid cell? a triploid cell?
- Do you know how we collected our F2 data?
- Can you distinguish phenotype groups in F2 seedlings and corn cobs?
- Can you make an accurate F2 count?
- Can you determine an observed ratio for F2 data?
- Can you figure out what Mendelian ratio it resembles?
- Can you calculate an entire chi-square table from raw data & a ratio to test?
- Given a ratio or data, can you determine df to use for your chi-square test?
- Using the chi-square probability table, can you evaluate chi-square test results?
- Knowing what ratio an F2 population fits, can you determine the genotypes of the F2? of F1? of P?
- Given the F2 ratio, can you determine the possible genotypes of a given F2 individual?
- Given an epistatic ratio, can you match genotype groups to phenotypes?
- Can you predict the appearance of Parentals and F1, given enough info about the F2??
- Can you tell if genes are independently assorted or linked given F2 data?
- Can you tell what type of dominance is shown given the Mendelian F2 phenotype ratio?
- Do you know the difference between corn, sorghum, and tobacco seedlings if you saw them?
- Can you make useful descriptive observations of mutant phenotypes??
- Can you discuss the implications of seedling and corn cob data for the genes/gene products involved? (you may
be speculating...)
- Can you make comparisons between our classroom data and what Mendel found? (discussion)
No problem? Then you're ready for the practical. Bring your calculator (no palm pilots or graphing calculators -- just a regular calculator).
