Meiosis Basics
This type of cell division produces gametes
Meiosis
This stage is when chromosomes first condense and homologous chromosomes pair up.
Prophase I
Two identical halves of a duplicated chromosome.
Sister Chromatids
This process during Prophase I swaps DNA between chromosomes.
Crossing over
This type of cell division produces identical body cells.
Mitosis
Meiosis reduces the chromosome number by half, producing these types of cells.
Homologous chromosomes line up in the middle of the cell during this stage.
Metaphase I
The point where sister chromatids are attached.
Centromere
The random way homologous chromosomes line up during Metaphase I.
Independent Assortment
This process produces four daughter cells
Meiosis
Meiosis has this many total divisions.
Homologous chromosomes separate during this stage.
Anaphase I
A pair of chromosomes that carry the same genes from each parent.
Homologous chromosomes
Genetic variation helps populations do this in changing environments.
Adapt/evolve
Crossing over occurs in this process but not in mitosis.
Meiosis (Prophase I specifically)
The cells produced by meiosis are used for this biological process.
Sexual reproduction
Sister chromatids separate during this stage of Meiosis II.
Anaphase II
The exchange of DNA between homologous chromosomes.
Crossing over
Humans have this many chromosomes in haploid gametes.
23
Mitosis results in cells with this chromosome number relative to the parent cell.
Same number (46)
Meiosis begins with this type of cell containing two sets of chromosomes.
Diploid cells
This is the final stage where four haploid cells form.
Telophase II (or Cytokinesis)
The structure formed when homologous chromosomes pair during Prophase I (hint: "4")
Tetrad
The random alignment of homologous chromosome pairs during this stage leads to independent assortment.
Metaphase I
This phase of meiosis is most similar to mitosis (Meiosis I or Meiosis II?)
Meiosis II
