What else can I help you with?
Do meisosis and mitosis have metaphase?
Mitosis for sure has metaphase. Scientists are guessing that meiosis has it too, but they combine it and make it "prometaphase," because prophase and metaphase happens so fast in meiosis.
In which phases of meiosis do the centomeres attch to spindle fibers?
Centromeres attach to spindle fibers during both meiosis I and meiosis II. In meiosis I, centromeres attach to spindle fibers during metaphase I, while in meiosis II, they attach during metaphase II. This attachment is crucial for the proper alignment and segregation of chromosomes during cell division.
How do chromosomes align differently in meiosis compared to mitosis?
In meiosis, chromosomes align in pairs during metaphase I, while in mitosis, chromosomes align individually during metaphase.
When does independent assortment occur in meiosis?
Independent assortment occurs in meiosis during metaphase I when homologous chromosomes align randomly at the metaphase plate. This allows for different combinations of alleles to be present in the gametes produced.
Does alignment of tetrads at metaphase plate occur in mitosis?
Yes, alignment of tetrads at the metaphase plate occurs in meiosis, specifically during meiosis I when homologous chromosomes pair up as tetrads. In mitosis, individual chromosomes align at the metaphase plate.
During which stage of meiosis are the bivalents arranged along the equator?
During the metaphase I meiosis are the bivalents are arranged along the equator. During the prophase I of meiosis I the crossing over occurs.

What stage of meiosis is when chromosomes line up in the center of the cell?
Chromosomes line up in the middle of the cell during meiosis.
What is the activity of chromosomes in metaphase 1 of meiosis?
In Mitosis during Metaphase, the chromosomes line up on the metaphase plate, but without their homologues. In Meiosis during Metaphase I, the tetrads line up on the metaphase plate. Then it's back to double-stranded chromosomes lining up in Metaphase II. I
During what phase of meiosis do replicated homologous chromosomes line up next to each other at the cell's equator-?
It is during the anaphase of meiosis that the replicated homologous chromosomes line up next to each other at the cell's equator.
How do chromosomes align differently in meiosis compared to mitosis?
In meiosis, chromosomes align in pairs during metaphase I, while in mitosis, chromosomes align individually during metaphase.
Does metaphase of mitosis meiosis 1 or meiosis 2 have the haploid number of chromosomes at the equator of the spindle?
Metaphase of meiosis 2 has the haploid number of chromosomes at the equator of the spindle. In meiosis 1, during metaphase, there are still pairs of homologous chromosomes lined up at the equator.
When does independent assortment occur in meiosis?
Independent assortment occurs in meiosis during metaphase I when homologous chromosomes align randomly at the metaphase plate. This allows for different combinations of alleles to be present in the gametes produced.
Does alignment of tetrads at metaphase plate occur in mitosis?
Yes, alignment of tetrads at the metaphase plate occurs in meiosis, specifically during meiosis I when homologous chromosomes pair up as tetrads. In mitosis, individual chromosomes align at the metaphase plate.
What happens to the tetrads in telophase?
During metaphase I of meiosis, tetrads line up along the equator of the cell. They are preparing for separation in the next phase.
What is the order of the phases of meiosis?
The order of the phases of meiosis is: prophase I, metaphase I, anaphase I, telophase I, cytokinesis, prophase II, metaphase II, anaphase II, telophase II, and cytokinesis. During meiosis I, homologous chromosomes separate, while during meiosis II, sister chromatids separate.
