What do you recall about meiosis and genetics? Since both of these areas have been discussed in past
science classes, we want to take a moment and let you explore what you remember! This document should
be re-visited after you copy lecture notes and after lectures. All items should become more concrete and
your comfort level go up! If they don’t, please come get assistance ASAP! 
Instructions: Be sure to READ these before you begin!
A. Log onto this website: http://www.phschool.com/science/biology_place/labbench/lab3/intro.html
(It will start comparing mitosis to meiosis as a starting point!)
B. As you work through each page, answer and perform the tasks on each page AND make sure you are
completing this document!
C. Read the introduction and then click “next”. (Again, be sure to complete ALL tasks asked for on the
screen as well as in this document!)
1. Look at the diagram comparing mitosis to meiosis and from what you can see, identify any 3 specific
differences in the processes.
2. What are “daughter cells” defined as?
3. What process makes “daughter cells”?
4. Why would we want those cells to be identical?
5. What is “n” and “2n” referencing?
6. Using a human, give an example of a diploid cell and a haploid cell?
7. Complete this sentence (using the term diploid or haploid): “________________ cells like sperm or egg,
undergo the process of meiosis to be created while ___________ cells like muscle cells undergo mitosis to be
created.
8. Looking at the diagram, which process ends with cells that have half as much DNA as the original cell?
Click Next Concept
9. Review the cell cycle as necessary by clicking through the “closer looks” until you get to the “Homologous
Structure” slide/picture. Feel free to read through the “closer looks” as needed to freshen up on the cell
cycle.
10. Using root words, what does “homo” mean in Latin?
11. Why do chromosomes that come from mom (maternal) and dad (paternal) need to be homologous?
12. What is an allele?
13. What scientist worked with pea plants and alleles and traits and became known as the “father of
genetics”?
14. Click next and review the details of mitosis as needed, skip the “timing of mitosis” activity and perform
the ending “mitosis quiz” to see that you remember mitosis well enough as we will be comparing mitosis to
meiosis soon. (Once done, check your answers and ask any questions you have!)
Click next
15. Being careful to use Roman numerals, list all the stages of meiosis in order that they occur.
16. What do you see is similar about the stages of meiosis?
17. What do you see is the major difference in the stages of meiosis?
Click Next Concept
18. What does n stand for? Therefore what would n be for humans?
19. How many chromosomes does each parent give you?
20. Define crossing over and synapse.
21. Draw a synapse on your paper.
22. What stage of meiosis does this crossing over occur?
Click Next Concept through the fungi experiment and when done taking “closer looks” through each slide,
continue to answer the questions.
23. What happens to genetic diversity of the sex cells of the fungi having gone through meiosis?
24. During what stage if meiosis did the diversity occur?

Stop when you get to the “Analysis of results II” and try to complete the 5 lab questions. Click previous as
needed to reread any of the lab information.
Click Next and complete the “comparison of mitosis and meiosis” being sure once you complete this you
check your answers and understand why you missed what you did.
Click Next and complete he last lab quiz, again, doing it first and then checking your answers and making
sure you know why you missed what you did!
Once done, use the space below to write out at least 5 questions you have over meiosis! These will help you
focus on specifics during lecture!
