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.

Chromosomes normally occur as homologous pairs in?
Chromosomes normally occur as homologous pairs in a diploid cell. These refers to matching pairs of chromosomes which are found in the cell.
At what stage does sister chromatid separation occur by mitosis and meiosis?
Sister chromatid separation occur in the Anaphase stage
Do homologous chromosomes separate only in meiosis?
yes. in mitosis there is separation of sister chromatids
What is the name given to the points along the length of homologous chromosomes where they remain held together in metaphase 1 just before their complete separation?
Centrioles
Which is the process during meiotic cell division where there is a separation of homologous pairs of chromosomes?
Homologous chromosomes are chromosomes that carry genes that perform the same functions. Seperation of these chromosomes occurs during Mitosis where sister chromatids will be separated and pulled to opposite sides of a dividing cell. It also occurs during Meiosis 1 and 2 where in meiosis homologous chromosome pairs will line for the first time on the metaphase plate and be pulled to opposite sides of the cell and once again (without duplicating again) line up on the metaphase plate and be pulled to opposite ends of the cell. So the separation of homologous chromosomes happens in Meiosis stage 1 where you have a diploid organism with 4 copies of its chromatids and these homologous chromosomes (chromatids connected by a centromere) are pulled to opposite ends of the cell.
What happens with incorrect separation of a homologous pair during meiosis?
a trisomy
Chromosomes normally occur as homologous pairs in?
Chromosomes normally occur as homologous pairs in a diploid cell. These refers to matching pairs of chromosomes which are found in the cell.
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"
At what stage does sister chromatid separation occur by mitosis and meiosis?
Sister chromatid separation occur in the Anaphase stage
Crossing over and the separation of duplicated homologous chromosomes in the first division produce genetic variation?
true
Do homologous chromosomes separate only in meiosis?
yes. in mitosis there is separation of sister chromatids
Could crossing over occur during second meiotic division?
No, tips of homologous chromosomes cross over in Meiosis I. There are no homologous chromosomes by Meiosis I.
Separation can occur both in what?
Peacetime and wartime
When does synapsi occur?
when two of homologous chromosomes form a tetrad sister chromatids and crossover
What happens in meiosis one that does not occur in meiosis?
the synapsis and crossing over of homologous chromosomes
What happens in meosis 1 that does not occur in meosis 2?
Pairing between homologous chromosomes
