MEIOSIS 1 and 2 By christopher caluori

MEIOSIS 1 -

All homologues move away from their partners and go into 2 new nuclei. The cytoplasm divides, and there are 2 daughter cells, with one of each type of chromosomes. The chromosomes are duplicated

MEIOSIS 2 -

All homologues move away from their partners and go into 2 new nuclei. The cytoplasm divides, and there are 2 daughter cells, with one of each type of chromosomes. The chromosomes are duplicated

Prophase 1-

The chromosomes begin to condense as new microtubules form a bipolar spindle

Prophase 2

One of the two centrioles move to the opposite side of the cell and a new bipolar spindle forms

Metaphase 1

A tug of war has aligned the chromosomes midway between the 2 spindle poles

Metaphase 2

The duplicated chromosomes are midway between the poles

Anaphase 1

One of the each duplicated maternal or paternal chromosome moves to a spindle pole. Motor proteins and microtubules allow for this movement to occur

Anaphase 2

The sister chromatids of each chromosome become individual chromosomes. Microtubules pull them to opposite poles, and other microtubules push the poles further apart

Telophase 1

One of each type of chromosome arrives at the pole. In most cases, the cytoplasm divides at this time

Telophase 2

There are now 4 nuclei , and the cytoplasm divides
