Meiosis Flashcards

Front 1

Meiosis 1

Back 1

homologous chromosomes are separated into two daughter cells ; follows stages similar to Mitosis.

Front 2

Prophase 1

Back 2

Chromosomes form and each chromosome pairs with its homologous chromosome; called a tetrad (four chromatids) In a tetrad, homologous chromosomes can exchange portions of their chromatids; called crossing over.

Front 3

Metaphase 1

Back 3

Tetrads line up in the middle, equatorial plane,of the cell

Front 4

Anaphase 1

Back 4

Homologous chromosomes separate and move away from each other to opposite poles of the cell. Each is genetically different from the original cell due to crossing over.

Front 5

Telophase & Cytokinesis 1

Back 5

nuclear envelope forms ; cytokinesis occurs resulting in two daughter cells. Daughter cells are NOT identical due to crossing over in prophase 1

Front 6

Meiosis 2

Back 6

sister "recombinant" chrimatids are seperated into four gamete cells; follows stages similar to mitosis.

Front 7

Prophase 2

Back 7

chromosomes form; nuclear envelope disappears

Front 8

metaphase 2

Back 8

chromosomes line up in the middle of the cell at the equatorial plate.

Front 9

Anaphase 2

Back 9

Sister chromatids separate and move away from each other to opposite poles of the cell

Front 10

Telophase & Cytokinesis 2

Back 10

nuclear envelope forms; Cytokinesis occurs resulting in four genetically different gametes
