What are the steps of meiosis?

Answer 1

• Prophase I: chromosomes start to condense and become visible
• Metaphase I: homologous chromosomes line up at equatorial plate
• Anaphase I: homologous chromosomes separate and move to diferent poles
• Telophase I: one set of chromosomes arrive at each pole
• Prophase II: chromosomes condense again
• Metaphase II: individual chromosome line up at equatorial plate
• Anaphase II: centromere divides, and chromosomes (from chromatids) move to different poles
• Telophase II: one set of chromosome arrive at each pole.

Answer 2

Meiosis occurs when human cells reproduce. I'm not 100% sure of the accuracy here, but this is sure to serve as a basic outline.

Prophase I - chromosomes link together to form a tetrad shape. Crossing over of genes is possible here. The chromatin condense into chromosomes, the nucleolus disappears, the nuclear membrane disassembles, and the spindle apparatus forms.

Metaphase I- tetrads line up on the equator of the spindle apparatus, the fibers attach to opposite sides of the centromere and the spindle fibers attache to the kinetochore fibers.

Anaphase I - Tetrads separate and are drawn to opposite poles by the spindle fibers, centromere remain intact.

Telophase I - Chromosomes reach poles of respective spindles. One set of chromosomes in each of the two cells. Chromosomes uncoil, nucleolus reforms, some cells have division of centrioles!:)

Prophase II- Nuclear envelope redissolves, spindle fibers reform, chromatin condenses, centrioles dived, kinetochore fibers form.

Metaphase II - Chromosomes migrate to equator of spindle. Spindle fibers attach to kinetochore fibers.

Anaphase II - Centromeres split, chromosomes are segregated into opposite sides of the cell.

Telophase II- chromosomes reach poles, nuclear envelopes reform, chromosomes uncoil, nucleolues reforms, cytokinesis occurs.

Yay! Now we have four cells, each with half as many chromosomes as the original cell!:)

SIMPLER VERSION:

Interphase - grows/developes

cromosones(X) double, fibers form

Prophase - nucleor membrane breaks

X thicken/visible

Metaphase - X pair up & line up

Anaphase - X move to opposite sides

Telephase - nucleor membrane reforms

2 cells form

Prophase2 - X not copied

Metaphase2 - X line up

Anaphase2 - X split/separate

Telephase2 - nucleor reforms

cell seperates

There are now 4 cells, each has 1/2 as many X as the original cell

Answer 3

Meiosis consists of two consecutive divisions, known as meiosis I and meiosis II. In meiosis I, homologous chromosomes pair up and exchange genetic material in a process called crossing over. The pairs then separate into two daughter cells. In meiosis II, the duplicated chromosomes split into chromatids, resulting in a total of four unique haploid daughter cells.
