diploid
number of chromosomes in mitosis
haploid
number of chromosomes in meiosis
identical
genetic similarity for mitosis
varied
genetic similarity for meiosis
gametes
purpose for meiosis
growth and repair
purpose for mitosis
so offspring have different combination of characteristics from the parents
meiosis increases variation why
1. independent segregation of chromosomes
2. recombination of homologous chromosomes by crossing over
how does meiosis increase variation
the combination of chromosomes that go into daughter cells in both meiosis one and two is random
what is independent segregation of chromosomes
when homologous chromosomes associate adjacent chromatids twist
cross-over
during a cross-over when chromatids break and recombine to form a new combination of alleles
recombination
chromosomes invisible; DNA replicates
mitosis: interphase
chromosomes appear, nucleus disappears
mitosis: prophase
chromosomes at equator, spindle forms
mitosis: metaphase
chromatids at poles, nucleus reforms
mitosis: telophase
cytoplasmic division
mitosis: cytokinesis
growth, differentiation, and repair
importance of mitosis
the result of mutations to the genes that regulate the cell cycle
cancer
prevents DNA replication
cancer treatment
Daughter cell grows and organelles duplicate
What happens during G1 stage?
DNA replicates
What happens during the S stage?
The cell checks the DNA and makes any repairs, and the cell prepares for division.
What happens during the G2 stage?
Mitosis helps cell reproduction, general growth, and repairing the body.
What is the importance of mitosis in the life cycle of a cell or organism?
Meiosis helps genetic diversity through sexual reproduction.
What is the importance of meiosis in the life cycle of a cell or organism?
asexual
What type of reproduction does mitosis use?
sexual
What type of reproduction does meiosis use?
tissue and organ cells
What types of cells undergo the process of mitosis?
reproductive system cells
What types of cells undergo the process of meiosis?
diploid somatic
What type of cells are produced by mitosis?
haploid gamete
What type of cells are produced by meiosis?
the homologous chromosomes independently assort
How do homologous chromosomes line up during prophase of mitosis?
the homologous chromosomes goes through a process called synapsis
How do homologous chromosomes line up during prophase of meiosis?
they align at the metaphase plate
What kind of behavior of homologous chromosomes does mitosis have during metaphase?
tetrads
What kind of behavior of homologous chromosomes does meiosis have during metaphase?
one
Number of nuclear divisions during mitosis
two
Number of nuclear divisions during meiosis
yes
Does replication of DNA occur in mitosis?
yes
Does replication of DNA occur in meiosis?
once
How many times does cytokinesis occur during mitosis?
twice
How many times does cytokinesis occur during meiosis?
two daughter cells
How many daughter cells are present at the end of mitosis?
four haploid daughter cells
How many daughter cells are present at the end of meiosis?
identical- 2N yields 2N; sometimes- N yields N
In mitosis, what is the “mother” cell’s genetic makeup compared to the daughter cells’ genetic makeup?
haploid- 2N yeilds N
In meiosis, what is the “mother” cell’s genetic makeup compared to the daughter cells’ genetic makeup?
