How does the principle of segregation apply to the movement of chromosomes in meiosis?

I'm not positive (get this verified), but I think you're talking about the process of random alignment in Metaphase I of meiosis. Basically, as the homologous chromosomes line up in the center of the cell, each homologue faces a side, but the side they face is random. So instead of all of the mother homologues facing one side and the father homologues facing another, some face one side, and some face the other. This helps to enlarge the variety of gametes that can be made during meiosis. Hope this helps!

What is random distribution of homologous chromosomes during meiosis called?
Segregation distortion, non-mendelian segregation.
When alleles on homologous chromosomes move into different gametes during meiosis this demonstrates?
Segregation
According to Mendel’s law of segregation, what happens to chromosomes during meiosis?
According to mendel's law of segregation, what happens to chromosomes during meiosis is that, allele pairs do separate leaving each and every cell with a single allele for each trait.
What is the law that states that each pair of chromosomes separates on its own in meiosis?
The law that states that each pair of chromosomes separates on its own in meiosis is known as Mendel's Law of Independent Assortment. This principle states that the inheritance of one trait does not affect the inheritance of another trait, as long as they are located on separate chromosomes. As a result, each pair of homologous chromosomes separates independently during meiosis, leading to genetic variation in the offspring.
How does mitosis differ from meiosis in terms of chromosome segregation?
Meiosis results in four cells, each with half the chromosomes of the original cell. Mitosis results in two cells, each which has the same number of chromosomes as the original cell.
Steps in meiosis that increase variability?
crossing over of chromosomes, indepependent segregation of chromosomes and mutations

Segregation
What is unique to mitosis and not a part of meiosis?
homologous chromosomes behave independently Pairing of homologous chromosomes allowing independent segregation and crossing over is unique to meiosis. In mitosis, homologous chromosomes behave independently.
What happens to chromosomes during meiosis According to Mendel law of segregation?
According to mendel's law of segregation, what happens to chromosomes during meiosis is that, allele pairs do separate leaving each and every cell with a single allele for each trait.
What happens to chromosomes during meiosis according to mendels law of segregation?

How does the principle of segregation relate to meiosis?
The pair of factors are separated during the formation of gametes.
Do homologous chromosomes separate only in meiosis?
yes. in mitosis there is separation of sister chromatids
Propose how crossing-over during meiosis might affect the segregation of genes that are on the same chromosomes?
Segregation is the separating of genes into different cells during meiosis. We have found that there are many more genes that display segregation than there are chromosomes. The explaination is crossing-over - where during prophase I chromosome arms of homologous chromosomes break off and attach to each other. This allows genes on the same chromosome to segregate.
What can we observe in order to visualize Mendel's Law of Segregation?
homologous chromosomes separating during meiosis I
