The one of the two matching pairs of chromosomes are separated during anaphase I.
Anaphase. My old biology teacher used to say you could remember it because the chromatids look like hands of bananas when they're being pulled apart. Banana sounds sort of like the 'ana' bit of anaphase if you pronounce it funny.
In Anaphase I
The phase you are referring to is metaphase I. In metaphase I of meiosis, homologous pairs of chromosomes line up at the cell's equator before they are separated and pulled to opposite ends of the cell during anaphase I.
During meiosis, tetrads, which are connected by a synapse partway down their length, line up along the cellular equator during metaphase I. The tetrads are then separated during anaphase I as the spindle fibers pull the tetrads apart towards opposite sides of the cell.

In anaphase I the duplicate paired chromosomes are separated. In anaphase II, the sister chromatids are separated.

In Anaphase I
Homologous chromosomes separate during meiosis I, specifically during the first stage called anaphase I. This separation ensures that each resulting daughter cell receives one copy of each homologous chromosome, contributing to genetic diversity in offspring.
Hello, Anaphase 1 and 2 are both part of the process of meiosis, the division of sex cells, and they are both phases where chromosomes are being pulled apart by the centrioles. However, in anaphase one the chromosomes are lined up in homologous pairs, meaning that there are two chromosomes side by side, so when the centrioles pull they are separating two unconnected chromosomes. In anaphase two the chromosomes are lined up in single file. So the centrioles are pulling one chromosome apart. It eventually breaks the link at the centromere of the chromosome and results in two sister chromatids. Hope this is clear enough to understand!

Anaphase 1: 1. Breakdown of proteins responsible for sister chromatid cohesion along chromatid arms allows homologs to separate. 2. The homologs move toward opposite poles, guided by the spindle apparatus. 3. Sister chromatid cohesion persists at the centromere, causing chromatids to move as a unit towards the same pole. At anaphase 1 of meiosis, the replicated chromosomes of each homologous pair move toward opposite poles, but the sister chromatids of each replicated chromosome remain attached. In anaphase of mitosis, by contrast, sister chromatids separate. Reference Cambell et al. Biology (8th Ed) 2008. Benjamin Cummings. pg 254-257
In mitosis, the homologous chromosomes dont interact, but in meosis, they separate during Anaphase 1. In mitosis, the homologous chromosomes dont interact, but in meosis, they separate during Anaphase 1.
