Although you studied mitosis and meiosis last year, it is worth a look again to make sure you have all the steps down correctly. This video explains how alleles are connected to the steps of mitosis and meiosis. I also assume this is familiar from last year.

Assignment 7
CREATIVELY answer the following questions on your own paper and photograph this and send it in through teams. Answer in full sentences and draw your answers.
1. What is Chromatin? How many strands are there in a human?
2. How many chromatids are there in a human?
3. What is the 2n or diploid number?
4. What is mitosis used for?
5. What is meiosis used for?
6. Define "Gamete"
7. What is the Haploid number?
8. What organ makes sperm, what makes egg?
9. How many chromatids are in a sperm or egg?
10 Draw a fertilization
11. Draw how sperm cells are made using the number 46 to represent the chromatid number.
12. Draw and label Chromatin, Chromatid, Sister chromatids, Chromosome. And show me a homologous chromosome
13. Draw a mitosis with 2n= 6. Label the stages in detail. Remember to draw Interphase and show chromatins.
14. Draw a meiois with 2n=6. Label the stages.
Again, draw interphase and show the chromatin.
15a. Why does crossing over happen during prophase I?
15b. What is primary nondisjunction. What can happen to the chromatid number?
16. The word chromosome is very tricky it's true definition is:
1 chromosome = 2 identical sister chromatids joined together in a centromere,
What is the other definition and why can it be a very tricky word?
17. Write the steps of meiosis and mitosis side by side. (this is at the end of the video)
You can also take a look at this resource. It is meiosis and mitosis from a college level text book. This is extended reading for those who are interested in going through biology. I think many of you can actually handle this level.
