|
is a two step process
|
|
Meiosis I
|
Reduction division
|
|
Meiosis II
|
Equational division
|
|
What happens in Interphase I
|
DNA replication
|
|
What happens in Prophase I
|
the nuclear envelop dissolves and the chromosomes become distinct as the DNA coils up
|
|
What happens in Metaphase I
|
Chromosomes will line up as pairs at the equator. this leads to the reduction from 46 to 23 chromosomes in the cell
|
|
What happens durning Anaphase I
|
twenty-three chromosomes (one member of each pair) will move towards each of the paired centrioles located at the cell's poles.
|
|
What happens during Telephase I
|
Teh chromosomes finish their migration towards the centrioles and cytokinesis divides the cell into two separate daughter cells.
|
|
What happens in Prophase II
|
the centrioles multiply and move to the poles of the cell
|
|
What happens in Metaphase II
|
the chromosomes line up single-file at the equator of the cell. the astral ray fibers attach to the centromere of each chromosome
|
|
What happens durning Anaphase II
|
the chromatids from the 23 chromosomes separate and move to the centrioles on the opposite sides of the cell
|
|
What happens in Telophase II
|
The chromosomes complete their migration into the daughter cells, and the nuclear envelop reforms.
|
|
What is crossing over
|
the members of a chromosome pair will exchange comparable pieces of thier SNA with one another.
|
|
