That would be anaphase I of meiosis. We know the question is concerning meiosis and not mitosis because it involves homologous chromosomes. Anaphase I begins when the kinetochore fibers stemming from the centrioles "grab" the centromeres of homologous chromosomes and "pull" them towards opposite ends of the cell.
The mechanisms are a little more complicated than "grabbing" and "pulling," but for this question the mechanisms are of little importance.
The phase where each chromosome is connected to a spindle fiber is called metaphase. During metaphase, the chromosomes align at the metaphase plate at the center of the cell, and each chromosome is attached to spindle fibers emanating from opposite poles of the cell.
Homologous chromosomes do not align themselves specifically at the left or right of the spindle during meiosis. Instead, they align along the metaphase plate in the center of the cell during metaphase I, where they can be separated into different daughter cells. This alignment is random, leading to genetic variation in the resulting gametes.
Chromosomes separate during cell division through a process called mitosis or meiosis. In mitosis, the duplicated chromosomes align at the center of the cell and are then pulled apart by the spindle fibers, ensuring each daughter cell receives a complete set of chromosomes. In meiosis, the process is more complex, involving two rounds of divisions to produce gametes with half the number of chromosomes.

Chromosomes line up in the middle of the cell during meiosis.
Homologous pairs of chromosomes line up in the middle of the spindle during meiosis I in the metaphase stage. This alignment is essential for ensuring proper segregation of chromosomes into daughter cells.

The phase where each chromosome is connected to a spindle fiber is called metaphase. During metaphase, the chromosomes align at the metaphase plate at the center of the cell, and each chromosome is attached to spindle fibers emanating from opposite poles of the cell.
Spindle fibers, also known as microtubules, are hollow protein fibers involved in the movement of chromosomes during cell division. These fibers form the spindle apparatus, which helps separate the chromosomes and pull them to opposite ends of the cell during both mitosis and meiosis.
yes, the spindle fibers are connected to a protein in the center of the chromatid called a kinetochore, and it is during metaphase that they line up on the metaphase plate (equator). It is then during anaphase that they start to move toward opposite poles. And the spindle fibers are connected to centrioles and in prophase before they separate they are called a centrosome.
Chromosomes separate during cell division through a process called mitosis or meiosis. In mitosis, the duplicated chromosomes align at the center of the cell and are then pulled apart by the spindle fibers, ensuring each daughter cell receives a complete set of chromosomes. In meiosis, the process is more complex, involving two rounds of divisions to produce gametes with half the number of chromosomes.
Chromosomes align at the center of the spindle during the metaphase stage of mitosis. This ensures that each chromosome is properly attached to the spindle fibers and aligned in a straight line to ensure accurate chromosome segregation during cell division.
During metaphase, the centromeres of chromosomes attach to spindle fibers (microtubules) that extend from opposite poles of the cell. This attachment helps properly align the chromosomes along the metaphase plate in the center of the cell before they are separated in anaphase.

The centromere is a region of a chromosome that plays a critical role in cell division. It is responsible for ensuring proper segregation of chromosomes during mitosis and meiosis. The centromere serves as the attachment site for spindle fibers that help pull apart sister chromatids.
