Metaphase I
Homologous chromosome line up in the center of the cell
Telophase I
Spindle fibers pull homologous pairs to ends of the cell
Telophase II/ Cytokinesis
4 haploid (N) daughter cells form
S Phase
Cells undergo a round of DNA replication
Anaphase II
Sister chromatids separate from each other
Telophase I/ Cytokinesis
2 haploid (N) daughter cells form
Prophase I
Spindle fibers attach to the homologous chromosome pairs
Telophase II
Individual chromatids move to each end of the cell
Prophase I
Crossing-over (if any) occurs
In meiosis, 4 haploid daughter cells are formed. In mitosis, 2 diploid daughter cells are formed
Compare the number and types of cells that result from meiosis vs. mitosis
In mitosis, each daughter cell has the same amount of chromosomes as the starting cell. In meiosis, each daughter cell has half of the amount as the starting cell
How do the genetic contents of cells resulting from mitosis and meiosis differ?
Similar: meiosis I and meiosis II both undergo PMAT; the formation of daughter cells
Different: meiosis I is when homologous pairs separate, forms 2 haploid daughter cells
meiosis II is when sister chromatids separate, forms 4 haploid daughter cells
Describe a similarity and a difference between meiosis I and meiosis II
Each daughter cell will have 14 chromosomes
If a diploid cell containing 28 chromosomes undergoes meiosis, how many chromosomes will each daughter cell have?
Similar: mitosis and meiosis form daughter cells and undergo PMAT
Different: meiosis forms gametes, makes 4 haploid daughter cells and are genetically diff. because of crossing over
Mitosis forms somatic cells, makes 2 diploid daughter cells and are same
How are mitosis and meiosis similar and different?
Metaphase I
Homologous chromosome line up in the center of the cell
Anaphase I
The individual chromosomes move apart
Telophase II/ Cytokinesis
4 haploid (N) daughter cells form
Telophase I
Spindle fibers pull homologous pairs to ends of the cell
S phase (both meiosis and mitosis)
Cells undergo a round of DNA replication
Metaphase II/ Metaphase (meiosis and mitosis)
The chromosomes line up across the middle of the cell
Prophase (I and II) (mitosis and meiosis)
Chromosomes become visible
Anaphase (II) (mitosis and meiosis)
Sister chromatids separate from each other
Telophase I/ Cytokinesis
2 haploid (N) daughter cells form
Anaphase (II) (mitosis and meiosis)
Sister chromatids separate into individual chromosomes
Telophase (I and II) (mitosis and meiosis)
Nuclear envelope re-forms
Metaphase I
Spindle fibers attach to the homologous chromosome pairs
Telophase (II)/ Cytokinesis (mitosis and meiosis)
Individual chromatids move to each end of the cell
Prophase/ I/II
The nucleolus disappears and the nuclear envelope breaks down
Prophase/I/II
Each chromosome is connected to a spindle fiber
