Chromosomes Homologous Nuclear Envelope Move Opposite Poles Leading

Front What are the stages of Meiosis 1
Back Interphase: Chromosomes copied
Prophase: Homologous chromosomes
shorten and thick and pair up, the nuclear envelope breaks down and centrioles move to opposite poles. Chiasmata occurs leading to a new combination of alleles leading to genetic variation
metaphase: spindle attaches to the centromere
homologous chromosomes align in the centre
Anaphase: Spindle contracts homologous chromosomes move to the opposite poles.
Chromosomes number halves
Independant segregation can occur here as it is completely random.
Telophase: Cytoplasm divides
nuclear envelope forms
homologous chromosomes
become
long and thin
