Crossing over occurs during this phase of meiosis I
What is prophase I?
100
At the end of this phase of meiosis II, there are 4 haploid nuclei.
What is telophase II?
100
When a chromosome makes a copy of itself, the two copies join together, forming an X. Each strand of the X is known as a...
What is a chromatid?

Mitosis produces cells with the same number of ___________________, but meiosis does not.
What is chromosomes?
200
During this phase of meiosis I, homologous pairs of chromosomes line up along the center of the cell
What is metaphase I?
200
During this phase of meiosis II, replicated chromosomes line up along the center of the cell.
What is metaphase II?
200
Because you inherit chromosomes from both parents, most of your cells have 2 copies of each chromosome. These cells can be described as...
What is diploid?
200
Mitosis has only one __________________, but meiosis has two.
What is (nuclear/cell) division?
300
During this phase of meiosis I, the homologous pairs are separated, with each homolog moving to a different side of the cell.
What is anaphase I?
300
During this phase of meiosis II, the nuclear envelope dissolves and the spindle fibers reappear.
What is prophase II?
300
One important difference between sister chromatids and homologous chromosomes is that sister chromatids are _______________________, while homologous chromosomes are not.
What is genetically identical (or exact copies)?

Mitosis produces two new cells, but meiosis produces ________ new cells.
What is four?

During this phase of meiosis I, the nuclear envelope reforms around two groups of replicated chromosomes.
What is telophase I?
400
During this phase of meiosis II, the two chromatids of each replicated chromosome are pulled apart and moved to opposite sides of the cell.
What is anaphase II?
400
This is the number of chromosomes in each daughter cell after a human cell completes mitosis.
What is 46?

At the end of meiosis II, the cells have only a single copy of every chromosome instead of pairs of chromosomes. These cells are described as...
What is haploid?
500
This is the number of chromosomes in each of the gametes produced after a human cell completes meiosis.
What is 23?
