- Telophase 2 and Cytokinesis
- meiosis 2 result in 4 haploid daughter cells
- Metaphase 1
- spindle fibers attach to the chromosome
- Crossing-over
- when homologous chromosomes exchange portions of their chrmatids during meiosis
- Prophase 1
- each chromosome pairs with its corresponding homologous chromosome to form a tetrad
- Haploid
- cell that contains only a single set of chromosomes and only a single set of genes
- Interphase 1
- cells undergo a round of DNA replication formng duplicate chromosomes
- Homologous
- chromosomes that each have a corresponding chromosome from the oppisite sex parent
- Diploid
- cell that contains both sets of homologous chromosomes
- Meiosis
- when the numbers of chromosomes per cell is cut in half through the separation of homologus chromosomes in a diploid cell
- Telophase 1 and Cytokinesis
- nuclear membranes form and the cell separates into two cells
- Anaphase 2
- the sister chromatids separate and move toward opposite ends of the cell
- Prophase 2
- meiosis 1 results in two haplid daughter cells each with half the number of chromosomes as the original cell
- Tetrad
- structure containing 4 chromatids that forms during meiosis
- Anaphase 1
- The fibers pull the homologous chromosomes toward opposite ends of the cell
- Metaphase 2
- the chromosomes line up in a simila way to the metaphase stage of mitosis
