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 |
