Sister chromatids are identical while homologous chromosomes are merely similar.
They are different because they separate the cells and then they become babies but only the homologous chromosomes do.
Somatic cell chromosome is made of two identical chromatids
In prophase I, doubled homologous chromosomes group together to form a tetrad.
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!
the chromosomes will move in the equatorial plane
a. chromatids do not separate at the centromere in anaphase I. b. centromeres do not exist in anaphase I. c. crossing-over occurs only in anaphase of miitosis

Homologous chromosomes are individual chromosomes inherited from each parent. Sister chromatids are the result of DNA replication, and the are identical.
Sister chromatids are exact copies of each other produced during DNA replication in a cell, connected at the centromere. Homologous chromosomes are pairs of chromosomes that carry the same genes in the same location, but may have different alleles. Sister chromatids are produced in preparation for cell division, while homologous chromosomes are inherited from each parent.

Sister chromatids are more similar to each other because they are exact copies of each other formed during DNA replication. Homologous chromosomes, on the other hand, are pairs of chromosomes that contain genes for the same traits, but may have different versions of those genes.
when two of homologous chromosomes form a tetrad sister chromatids and crossover
Homologous chromosomes is a pair made of a paternal and maternal chromosomes. But sister chromatid is either pairs of paternal or maternal chromosomes
Crossing over results in nonidentical sister chromatids of homologous chromosomes.
A bivalent at the beginning of prophase I is composed of two homologous chromosomes that have already replicated into sister chromatids. Each homologous chromosome consists of two sister chromatids joined by a centromere. The bivalent forms as the homologous chromosomes pair up and undergo synapsis.
A tetrad consists of two homologous chromosomes, each composed of two sister chromatids. This results in a total of four chromatids aligned during meiosis, allowing for genetic recombination between the homologous chromosomes.
In anaphase I of meiosis, the homologous pairs of chromosomes separate. Due to DNA replication and crossing over during prophase I, these chromosomes consist of a pair of non-identical sister chromatids. During anaphase II of meiosis, the sister chromatids separate into individual chromosomes.
The homologous chromosomes (as pairs of sister chromatids) separate to opposite poles of the cell.
