This is a term that means "the same as". If a certain substance is termed homologous then it means made up of the same material. Therefore, it won't be able to separate because it is only made from the one thing (one atom, one molecule etc.) Heterogenious is when something is made of more than a single type of thing.
What else can I help you with?
When does the first cell division in meiosis occur?
The first cell division in meiosis, known as meiosis I, occurs after the DNA in the cell has been replicated during the S phase of the cell cycle. Meiosis I involves the separation of homologous chromosomes.
Do homologous chromosomes separate only in meiosis?
Yes, homologous chromosomes separate only during the first division of meiosis, known as meiosis I. This separation ensures that each daughter cell receives one complete set of chromosomes.
What phase do homologues separate?
Homologous chromosomes separate during anaphase I of meiosis. This phase occurs after the homologous chromosomes have lined up along the metaphase plate during metaphase I. The separation of homologous chromosomes ensures that each daughter cell receives a complete set of chromosomes.
Chromosomes normally occur as homologous pairs in?
Chromosomes normally occur as homologous pairs in diploid cells, with one chromosome in each pair inherited from each parent. These pairs are similar in terms of size, shape, and genetic content, allowing for genetic diversity and recombination during sexual reproduction. Homologous chromosomes carry the same genes, but may have different variants (alleles) of those genes.
What phase will homologous chromosomes move away from each other?
Homologous chromosomes move away from each other during anaphase I of meiosis, which is when the spindle fibers pull the homologous chromosomes to opposite poles of the cell. This separation allows each daughter cell to receive a complete set of chromosomes.
What happens with incorrect separation of a homologous pair during meiosis?
Incorrect separation of a homologous pair during meiosis can lead to aneuploidy, where a cell has an abnormal number of chromosomes. This can result in genetic disorders or developmental abnormalities in the offspring.
What occurs in meiosos but not in mitosis?
lining up of tetrads, crossing over, and separation of homologous chromosomes.
What is the separation of homologous pairs of double chromosomes during meiosis?
the stage is called the "first division"
When does the first cell division in meiosis occur?
The first cell division in meiosis, known as meiosis I, occurs after the DNA in the cell has been replicated during the S phase of the cell cycle. Meiosis I involves the separation of homologous chromosomes.

What phase do homologues separate?
Homologous chromosomes separate during anaphase I of meiosis. This phase occurs after the homologous chromosomes have lined up along the metaphase plate during metaphase I. The separation of homologous chromosomes ensures that each daughter cell receives a complete set of chromosomes.
What happens in meosis 1 that does not occur in meosis 2?
Pairing between homologous chromosomes
What happens in meiosis one that does not occur in meiosis?
the synapsis and crossing over of homologous chromosomes
When does synapsi occur?
when two of homologous chromosomes form a tetrad sister chromatids and crossover
Separation can occur both in what?
Peacetime and wartime
When do Homologous chromosomes separated?
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.
