Is metaphase a phase in mitosis or meiosis?
Metaphase is a phase in both mitosis and meiosis.
How does metaphase in meiosis differ from metaphase in mitosis?
In metaphase of meiosis, homologous chromosomes line up in pairs, while in metaphase of mitosis, individual chromosomes line up singly.
What is the difference between metaphase in mitosis and metaphase I in meiosis?
In metaphase of mitosis, chromosomes line up in the middle of the cell, while in metaphase I of meiosis, homologous chromosomes line up in pairs.
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.
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.
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 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
What are the differences in the occurrence and significance of metaphase in meiosis compared to mitosis?
In meiosis, metaphase occurs twice (metaphase I and metaphase II) while in mitosis, it occurs only once. The significance of metaphase in meiosis is to ensure proper separation of homologous chromosomes in metaphase I and sister chromatids in metaphase II, leading to genetic diversity. In mitosis, metaphase ensures accurate alignment of chromosomes for equal distribution to daughter cells, maintaining genetic stability.
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.
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.
How is metaphase I of meiosis different from metaphase of mitosis in terms of chromosome alignment and segregation?
In metaphase I of meiosis, homologous chromosomes align in pairs at the cell's equator, while in metaphase of mitosis, individual chromosomes align singly. Additionally, in metaphase I of meiosis, homologous chromosomes segregate to opposite poles, whereas in mitosis, chromosomes segregate randomly to the daughter cells.
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.
