It's just a phase
During this phase, homologous chromosomes line up down the middle of a cell. (Include a number.)
What is metaphase 1?
Mitosis or Meiosis:
Two identical cells are made.
What is mitosis?
Chromosomes that contain the same information are called this. You receive one set from mom and one set from dad.
This is the meaning of "haploid".
What is . . .
a cell that has half the normal number of chromosomes.
(So that it can be combined with another haploid cell to make a baby.)
This is the most popular pizza topping among Americans.
What is pepperoni?
During this phase sister chromatids pull apart. (Include a number).
What is anaphase 2.
Mitosis or Meiosis:
The product is unique haploid gametes.
What is meiosis?
During metaphase 2, these parts line up down the middle of the cell.
What are sister chromatids?
The diploid number of chromosomes for corn is 20. This is the number of chromosomes that should be in a corn pollen (sperm) cell.
What is 10?
These two words were combined to make the name "Spam"
What is "spiced ham"?
This is the phase where crossing over occurs. (Include a number)
What is metaphase 1?
Mitosis or Meiosis:
There are two rounds of cell division.
What is meiosis.
This is what happens during crossing over.
Some information is traded between homologous chromosomes.
This term means a version of a gene for a trait. For example A or a.
What is an allele?
Name a meat that was served at the first Thanksgiving dinner.
- Venison
- Lobster
- Oysters
-Duck
- Goose
Beginning with interphase, list the stages of meiosis in order.
What is: interphase, prophase 1, metaphase 1, anaphase 1, telophase 1, prophase 2, metaphase 2, anaphase 2, telophase 2.
(You may have also included cytokinesis after each telophase.)
Name something that happens during both mitosis AND meiosis.
Check each other. Possible answers:
- Both are types of cell division
- DNA is replicated before both processes
- Similar steps (metaphase, anaphase, etc.)
When is the DNA in its chromatin form?
What is . . . during interphase?
These thread-like structures help to pull the chromosomes apart.
What are spindle fibers?
This was the first food eaten by an American in space.
What is applesauce?
Raise your hand and ask for a set of meiosis cards. Lay out the cards in order.
Check each other or ask Mrs. Brown to check your work.
How does meiosis produce cells with UNIQUE information?
There are two key ways:
1. Information is exchanged in crossing over. This can happen in MANY different gene locations.
2. The homologous chromosomes can line up in various ways during metaphase 1 causing different combinations when they separate.
This is the term for a group of homologous chromosomes that are next to each other for crossing over.
What is a tetrad?
This is how an organism's genotype relates to its phenotype.
the genotype is the type of genes the organism inherited. The information in the genotype determines what physical characteristics (phenotype) the organism shows.
If you suffer from mageirocophobia, you have a fear of this.
What is . . . a fear of cooking?
