Meiosis Flashcards
Meiosis
During meiosis, the number of chromosomes is halved so that each daughter cell has only one of each type of chromosome. This is necessary for sexual reproduction and also creates variation in the offspring
Interphase
The DNA is replicated
Cell Growth
Prophase 1
The chromosomes become visible
The homologous pairs come together and crossovers occur between a matching segment of one chromosome with a strand in its paired homologue
Metaphase 1
The chromosomes line up in the equator of the cell
Spindle forms
Anaphase 1
The whole chromosomes are pulled to each side by the spindles
Telophase 1
Two new nuclei is formed around the chromosomes
Cytokinesis 1
The cytoplasm splits into two complete cells
Prophase 2
A new spindle forms around the chromosomes
Metaphase 2
The chromosomes line up in the equator of the cell
Anaphase 2
The centromere divides and the chromatids are pulled apart to the side
Telophase 2
Four new nuclei is formed around each set of the chromosomes
Cytokinesis 2
The cytoplasm splits into four complete cells
