What step of meiosis in a diploid cell is shown above?
(Hint explains the picture) |
Prophase I (early)
|
The chromosomes begin to supercoil (condense) making them more visible.
|
|
What step of meiosis in a diploid cell is shown above?
(Hint explains the picture) |
Prophase I (late)
|
The chromatids' have supercoiled into matching chromosomes. The nuclear envelope disintegrates. Crossing over may happen (entirely random). Spindle microtubules have begun to form.
|
|
What step of meiosis in a diploid cell is shown above?
(Hint explains the picture) |
Metaphase I
|
The spindle microtubules move the homologous pairs to the equator of the cell. The orientation of paternal + maternal chromosomes is random and independent of other homologous pairs.
|
|
What step of meiosis in a diploid cell is shown above?
(Hint explains the picture) |
Anaphase I
|
The homologous pairs are separated. On chromosome of each pair moves to each pole.
|
|
What step of meiosis in the haploid cells is shown above?
(Hint explains the picture) |
Telophase I
|
Chromosomes uncoil then interphase follows. The chromosome number is reduced from diploid to haploid. Cytokinesis occurs.
|
|
What step of meiosis in the haploid cells is shown above?
(Hint explains the picture) |
Prophase II
|
Chromosomes, still consisting of two chromatids, condense and become visible.
|
|
What step of meiosis in the haploid cells is shown above?
(Hint explains the picture) |
Metaphase II
|
the spindle microtubules line up the chromosomes along the equator.
|
|
What step of meiosis in the haploid cells is shown above?
(Hint explains the picture) |
Anaphase II
|
Centromeres separate and chromatids are moved to opposite poles.
|
|
What step of meiosis in the haploid cells is shown above?
(Hint explains the picture) |
Telophase II
|
Chromatids reach opposite poles. Nuclear envelop forms. Cytokinesis occurs.
