How many chromosomes are in a human gamete?
If a eukaryotic cell has 20 chromosomes and it undergoes meiosis, how many cells will result, and how many chromosomes will they contain?
Cells that are ________ possess a single set of chromosomes
You have homologous pairs of chromosomes in each of your cells. In what way are these pairs of chromosomes similar?
What process produces genetic diversity through random distribution of maternal & paternal chromosomes(meaning they can line up on either side of the metaphase plate)?
From the list below, which choice represents a correct difference between sperm production and egg production?

An organism has 38 chromosomes in a body cell. After mitosis each cell has 38 chromosomes. After meiosis each gamete has ____________________ chromosomes.
An organism’s gametes have ____________________ the number of chromosomes found in the organism’s body cells.
Sister chromatids inside both cells get separated during this phase
Tetrads line up along the equator during this phase
At the end of meiosis I, ________ daughter cells are created.
At the end of meiosis I, the daughter cells created are DIPLOID or HAPLOID?
Meiosis occurs in what type of cells
Why does meiosis have two cell divisions? (HINT: Think of chromosome number) Why is this important for reproduction?
Explain why the daughter cells produced by meiosis are genetically different from each other, whereas the daughter cells produced by mitosis are not.
What two major events occur during meiosis that give the new cells genetic variation?
When does meiosis occur in girls? In boys?
Label the phases of Meiosis (be sure to be specific with I or II). Open the image below and insert text into the numbered boxes by clicking the "T" button on the toolbar to the right.
Though the stages of meiosis have the same names as the stages of mitosis, they exhibit fundamental differences. What are the main differences between the two processes?
What can you tell about the person that this karyotype is from? Choose ALL that apply.
In general, chromosomal mutations usually have much more serious consequences than single gene mutations (point mutations, frameshifts, etc). Explain why.
Identify each type of the chromosomal mutations in the image above. Use the "T" option to enter a text box.
