An organism has 38 chromosomes in a body cell. After mitosis each cell has 38 chromosomes. After meiosis each gamete has ____________________ chromosomes.

1

An organism’s gametes have ____________________ the number of chromosomes found in the organism’s body cells.

1

Sister chromatids inside both cells get separated during this phase

1

Tetrads line up along the equator during this phase

1

At the end of meiosis I, ________ daughter cells are created.

1

At the end of meiosis I, the daughter cells created are DIPLOID or HAPLOID?

1

Meiosis occurs in what type of cells

Short Answer: Answer the questions below using sentences, a model, or bullet-point list.

1

Why does meiosis have two cell divisions? (HINT: Think of chromosome number) Why is this important for reproduction?

1

Explain why the daughter cells produced by meiosis are genetically different from each other, whereas the daughter cells produced by mitosis are not.

1

What two major events occur during meiosis that give the new cells genetic variation?

1

When does meiosis occur in girls? In boys?

1

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.

1

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?

1

What can you tell about the person that this karyotype is from? Choose ALL that apply.

1

In general, chromosomal mutations usually have much more serious consequences than single gene mutations (point mutations, frameshifts, etc). Explain why.
