Homologous chromosomes are chromosome pairs of the same length, centromere position, and staining pattern, with genes for the same characteristics at corresponding loci. One homologous chromosome is inherited from the organism's mother; the other from the organism's father.[1]
They pair (synapse) during meiosis, or cell division that occurs as part of the creation of gametes.
Each chromosome pair contains genes for the same biological features, such as eye color, at the same locations (loci) on the chromosome. Each pair, however, can contain the same allele (both alleles for blue eyes) or different alleles (one allele for blue eyes and one allele for brown eyes) for each feature.
i answered my own question... =p
What else can I help you with?
Is homologous chromosomes only present in cells that undergo meiosis?
Usually they dont as homologous chromosomes form bivalents with other homologous chromosomes and crossing over occurs between the 2. But if a chiasmata does form between the t homologous chromosomes they can change information.
What is the difference between a haploid cell and the diploid cell?
A diploid cell differs from haploid is that the diploid cell has homologous chromosomes as when the haploid cell doesn't have homologous chromosomes.
What is the difference between a diploid cell and a haploid cell?
A diploid cell differs from haploid is that the diploid cell has homologous chromosomes as when the haploid cell doesn't have homologous chromosomes.
What are two functions of chiasmata?
Chiasmata are important for holding homologous chromosomes together during meiosis, facilitating genetic recombination between the chromosomes. They also help ensure proper segregation of chromosomes during meiosis by maintaining tension between homologous chromosomes.
Pairing of homologues and crossing over occur?
== == Yes That's correct In Meiosis Stage 2 The Chromosomes must in effect rip a little peice of each other off in order to conduct Mitosis Again and to make the last two gametes and Within a female it is used also to create Polar bodies in the female gamete cell Hope This Helped :]

Difference between sister chromatids and homologous chromosomes?
Homologous chromosomes are individual chromosomes inherited from each parent. Sister chromatids are the result of DNA replication, and the are identical.
What is the difference between a haploid cell and the diploid cell?
A diploid cell differs from haploid is that the diploid cell has homologous chromosomes as when the haploid cell doesn't have homologous chromosomes.
What is the difference between a diploid cell and a haploid cell?
A diploid cell differs from haploid is that the diploid cell has homologous chromosomes as when the haploid cell doesn't have homologous chromosomes.
What does the term chiasma refer?
In biology, chiasma refers to the site where genetic material is exchanged between homologous chromosomes during meiosis. This process, known as crossing over, increases genetic diversity by shuffling genetic information between chromosomes.
What are chromosomes that have the same length and carry genes for the same traits?
Homologous chromosomes are chromosomes that have the same length and carry genes for the same traits. One homologous chromosome is inherited from each parent. During meiosis, homologous chromosomes pair up, allowing for genetic material to be exchanged between them.
When does crossing over take place between homologous chromosomes during meiosis?
Crossing over between homologous chromosomes occurs during prophase I of meiosis.
What is the difference between homologues and analogues?
homologues= same function different origin analogues= same origin with possibly a different function
What is the difference between translocation and nondisjunction?
Nondisjunction is when a Chromosome is unable to separate correctly during cell devision. Translocation (In Chromosomes) is when an abnormality is caused by the rearrangement of parts between non-homologous Chromosomes.
What is the exchange of genes between homologous pairs of chromosomes?
The exchange of genes between homologous pairs of chromosomes is called genetic recombination. This process occurs during meiosis, where corresponding segments of DNA are exchanged between maternal and paternal chromosomes, increasing genetic variation in offspring.
Does crossing over produces chromosomes that carry genetic information from both homologous 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.
What trem describes the exchange of genetic material between members of a homologous pair of chromosomes?
Crossing over is the term that describes the exchange of genetic material between members of a homologous pair of chromosomes during meiosis. This process increases genetic diversity by reshuffling alleles between homologous chromosomes.
