Cell Cycle
A cell will spend most of its time in this part of the cell cycle
What is Interphase?
When Crossing Over occurs
What is Prophase I?
The end result of Meiosis
What is four genetically different haploid daughter cells?
A diploid cell of a panda bear has 42 chromosomes, how many would the haploid cell have?
What is deletion?
The phase of mitosis that involves chromosomes lining up in the middle of the cell
What is Metaphase?
When Independent Assortment occurs in Meiosis
What is Metaphase I?
A 2n parent cell has 20 chromosomes, how many would the daughter cell have after going through Meiosis?
What is 10?
The end result of Mitosis
What is two identical diploid daughter cells?
In this mutation a section of a chromosome is replicated
What is duplication?
Mitosis occurs after this phase of the cell cycle
What is G2 (or what is interphase)
Why is crossing over important to genetic variation in organisms?
To make body cells
To help with meiosis and the process of cell division
So that genetic information from each parent is shared with the offspring
To regulate cell division
What is #3-
So that genetic information from each parent is shared with the offspring
The type of cell that goes through Meiosis
What is Gametes/Reprodutive Cells/Body Cells
The type of cell that goes through Mitosis
What is Somatic Cells/Body Cells?
This is a mutation where a section is removed, reversed, and put back in the chromosome
What is Inversion?
Mitosis is
The formation of gametes
Division of nuclei
The formation of haploid cells
Responsible for synthesizing RNA
What is Division of nuclei
The independent assortment of homologous chromosomes during meiosis helps genetic variation. Which of the following best explains how this occurs?
Increases the likelihood of crossing over between non-sister chromatids.
Increases the likelihood of possible chromosome combinations in the gametes.
Results in the formation of some diploid and some haploid gametes.
Results in the formation of gametes that contain different numbers of chromosomes.
What is #2- increases the likelihood of possible chromosome combinations in the gametes.
The purpose of Meiosis
The purpose of Mitosis
What is Growth and Repair?
What is Translocation?
The phase of mitosis where the chromosomes are separated into chromatids
What is Anaphase?
The three causes of genetic variation in Meiosis
What is Crossing Over, Independent Assortment, and Radom Fertilization?
Two reasons Meiosis is important
Its allows organisms to reproduce sexually by reducing the number of chromosomes in gametes
Provides genetic variation among offspring so not two individuals are genetically the same
Allows body cells to divide and create new cells
Creates genetically identical diploid daughter cells.
What is #1- Its allows organisms to reproduce sexually by reducing the number of chromosomes in gametes
and #2- Provides genetic variation among offspring so not two individuals are genetically the same
Which is more important- Mitosis or Meiosis?
What is neither one- they are equally important?
This mutation is visible when looking at a Karyotype and finding a homologous pair that has too many or not enough chromosomes
What is Non Disjunction?
