What is the fourth stage of mitosis called?
a. Telophase
This is the stage a body cell spends most of it's life cycle.
Interphase
Are daughter cells genetically identical in meiosis?
b. No.
What is the stage after mitosis called?
b. Cytokinesis
Meiosis is used for just one purpose in the human body. What is it?
To make gamete cells for sexual reproduction.
What stage of Mitosis is this?
Anaphase
What's the difference between the types of cells being created in meiosis and mitosis?
In meiosis, haploid gametes (eggs & sperm) are created. In mitosis, skin cells, blood cells, and all somatic cells are making identical copies of themselves.
How many cells are created in mitosis? Are they haploid or diploid cells?
Mitosis creates 2 diploid cells
How many cells are created in meiosis? Are they haploid or diploid?
4 haploid cells
What stage of Mitosis is this?
Metaphase
What is the purpose of mitosis?
To grow, replace worn out cells, and repair tissues.
What happens in the third stage of mitosis?
d. Anaphase. In this stage, the sister chromatids separate into individual chromosomes and are pulled apart.
In humans, how many chromosomes does each gamete contain?
23 chromosomes
What stage of Mitosis is this?
Telophase
What is the purpose of meiosis?
Meiosis creates genetic variety in 4 haploid cells in order for the organism to reproduce.
In meiosis, what separates during anaphase I?
homologous chromosomes
The division of the cytoplasm to form two new cells
Cytokinesis
How many phases are there in meiosis and what are they?
8 phases: prophase I and II, metaphase I and II, anaphase I and II, telophase I and II
What phase of mitosis is this?
Interphase
What is crossing over and when does it happen?
Crossing over is when genes on homologous chromosomes swap. It happens during Prophase I of meiosis.
In meiosis, what separates in anaphase II?
sister chromatids
