Homologous chromosomes are two sister chomatids stuck together with cohesins forming a tetrad. They have the same genes but not necissarily the same alleles, so they could carry hair color, one with brown the other with blonde.
So, homologous chromosomes share the same gene.

similarities between kangaroo and human
There are zero similarities between the two.
Homologous chromosomes are individual chromosomes inherited from each parent. Sister chromatids are the result of DNA replication, and the are identical.
Crossing over involves the exchange of genetic material between homologous chromosomes during meiosis. Each homologous pair consists of four chromatids (two from each chromosome), and crossing over occurs between a pair of chromatids from each homologous chromosome. This results in the exchange of genetic material between the chromatids.
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.
Homologous chromosomes is a pair made of a paternal and maternal chromosomes. But sister chromatid is either pairs of paternal or maternal chromosomes
The question is not proper. Please define more. I assume you meant whether the genetic information is transferred between homologous chromosomes. Yeah it does. When the two homologous chromosomes pair up to form bivalents, crossing over occurs between them.
In meiosis, doubled chromosomes (homologous pairs) pair to form tetrads during prophase I. This allows for genetic recombination to occur between homologous chromosomes. In mitosis, chromosomes do not pair to form tetrads as there is no crossing over between homologous chromosomes.
During meiosis, sister chromatids of homologous chromosomes come together to form a structure called a tetrad. This allows for crossing-over to occur, where sections of genetic material are exchanged between the chromatids. This process increases genetic diversity in the resulting gametes.
Sister chromatids do not cross over. Cross over occurs between homologous chromosomes during meiosis I, where genetic material is exchanged between non-sister chromatids, leading to genetic variation in the offspring.
Recombinant chromatids have undergone genetic recombination, resulting in the exchange of genetic material between homologous chromosomes. This process can occur during meiosis. Parental chromatids, on the other hand, have not undergone genetic recombination and contain the original combination of alleles from the parent chromosomes.
Crossing over occurs between homologous chromosomes, which are not identical, as one member of each pair of homologous chromosomes comes from the mother, and one member comes from the father. Sister chromatids are identical and crossing over would have no effect.
-- synapsis: homologous chromosomes are coming close together and bivalents are formed.-- crossing-over: non-sister chromatids of homologous chromosomes interchange genesThe pairing (formation of bivalents) allows crossing over to take place and this enables genetic variations in the gametes.
This is called genetic recombination or crossing over. It results in the exchange of genetic material between homologous chromosomes during meiosis, leading to genetic diversity in offspring.
