Chromosomes Homologous Nuclear Envelope Move Opposite Poles Leading

Meiosis I involves prophase (shortened, thickened chromosomes, homologous pairs, chiasmata), metaphase (alignment of homologous chromosomes at the equator), anaphase (separation of homologous chromosomes to opposite poles), and telophase (cytoplasm division).

Meioza I implică profaza (cromozomi scurtați, îngroșați, perechi omoloage, chiasmă), metafaza (alinierea cromozomilor omologi la ecuator), anafaza (separarea cromozomilor omologi spre poli opuși) și telofaza (diviziunea citoplasmei).

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
