Introduction
The number of chromosomes you get from each parent.
What is 23 chromosomes?
2 cells.
How many cells are present at the end of meiosis 1?
One of these is NOT part of the chromosome. spindle, centromere, or chromatid
What is the spindle?
The term used to describe body cells made during MITOSIS.
What is a somatic cell?
A sperm cell is said to be this ploidy.
What is haploid?
This is a process that occurs during Prophase 1, only during Meiosis. It creates extra genetic diversity.
What is crossing over?
This is the number and type of cells made at the end of Meiosis 2.
What are 4 genetically unique haploid gametes?
The term used to describe the diploid cell created after the egg and sperm fuse.
What is a zygote?
A cell with 2 sets of chromosomes. Example: fertilized zygote.
What is a diploid cell?
The 8 stages of meiosis
What are Prophase I, Metaphase I, Anaphase I, Telophase I, Prophase II, Metaphase II, Anaphase II, and Telophase II?
The type of cells made during meiosis (not specific to gender).
What are gametes?
In Meiosis I, cells are haploid or diploid?
What is diploid?
Chromosomal structure allowing crossing over.
What is a tetrad?
After meiosis, are gametes genetically identical or different. Explain why.
What is genetically different because the chromosomes have crossed over and independently assorted.
The term used to describe a pair of chromosomes inherited from each parent.
What are homologous chromosomes?
A fertilized zygote has a set of each chromosome originating from each parent therefore the gametes have to be this.
Why are gametes haploid?
This law describes the fact that chromosomes are separated into chromatids randomly and separately for each chromosome.
What is the Law of Independent Assortment?
How are Anaphase I and Anaphase II different?
Anaphase I separates homologous chromosomes, Anaphase II, the sister chromosomes are separated.
