What happens during metaphase II quizlet?
What happens during metaphase II of meiosis? Sister chromatids are distributed in a single layer across the center of the cell. What happens during anaphase I of meiosis? Homologous chromosomes separate but sister chromatids remain joined at their centromeres.
Which of the following occurs in metaphase II?
The correct answer is (b) Chromosomes migrate to the middle of the cell. Just as in metaphase of mitosis, metaphase II of meiosis occurs when...
Why is metaphase II important?
In metaphase II, the second stage of meiosis II, in each of the two daughter cells produced by the first meiotic division (which are known as secondary germ cells), the spindle again draws the chromosomes to the metaphase plate.
What happens in metaphase I and metaphase II?
The main difference between metaphase 1 and 2 is that chromosomes are attached as homologous pairs at the equator during the metaphase 1 and during metaphase 2, single chromosomes are attached at the equator.
What occurs in metaphase 2 of meiosis?
During metaphase II, the centromeres of the paired chromatids align along the equatorial plate in both cells. Then in anaphase II, the chromosomes separate at the centromeres. The spindle fibers pull the separated chromosomes toward each pole of the cell.
What occurs in meiosis II?
During meiosis II, the sister chromatids within the two daughter cells separate, forming four new haploid gametes. The mechanics of meiosis II is similar to mitosis, except that each dividing cell has only one set of homologous chromosomes.
Is there metaphase 2 in mitosis?
The genetic structures in cells composed of condensed DNA ,which contain the genetic code for an organism. to be paired with. This metaphase looks similar to metaphase of mitosis but there is a key difference.
What is the difference between metaphase 2 of meiosis and metaphase of mitosis?
Hint: Meta means second and phase means stage, hence metaphase is the second stage of meiosis and mitosis....Distinguish between metaphase of mitosis and metaphase I of meiosis.Metaphase of mitosisMetaphase I of meiosisIndividual chromosome align at metaphase plateTetrad of chromosomes lie at the metaphase plate.5 more rows
Which of the following event occurs in meiosis 2?
In meiosis I these are known as prophase I, metaphase I, anaphase I and telophase I, while in meiosis II they are known as prophase II, metaphase II, anaphase II and telophase II. Different products are formed by these phases, although the basic principles of each are the same.
