How can crossing-over between two alleles be used to map their locations on chromosomes?

Crossing over during meiosis sometimes separates genes that had been on the same chromosome onto homologous chromosomes. Cross over events occasionally separate and exchange linked genes and produce new combinations of alleles...

This OS the wrong answer.
The answer should be:
The percentage of crossing-over for two traits is proportional to the distance between them on a chromosome. Sturtevant defined one map unit as a frequency of crossing-over of one percent.

What is the exchange of genes between homologous pairs of chromosomes?
homologous chromosomes exchange alleles during crossing over.
What is the relationship between alleles and chromosomes?
All chromosomes consist of genes and non coding material. Animals with chromosomes arranged in the double helix pattern have two almost identical genes on the chromosomes opposite from the other. When those two genes in particular are discussed, they are called alleles. Frequently one is expressed and one is not, or one is dominant and the other is not.
During meiosis the process of crossing over results in new combinations of alleles because?
genetic material is exchanged between chromosomes during this process.
What is the relationship between genes and alleles?
The gene loci are the sites where the alleles reside on the DNA strand. Alleles at the same gene locus on each chromosome pair will determine the phenotypic expression of that gene pair. Of course this explanation is incomplete when more complex interactions between alleles come into play
What is the relationships between chromosomes genes and alleles?
alleles are the various types of options that is chosen by the gene. The gene is the segment of DNA that codes for the protein. Genes are found on chromosomes. Chromosomes contain multiple genes.

Does cytokinesis provide new genetic combinations?
Yes. Crossing over (or recombination) shuffles sequences between homologous chromosomes. The resulting chromosomes have different combinations of alleles from the original chromosomes.
How can new combinations of alleles be created when genes are linked?
New combinations of alleles can be created when genes are linked through a process called crossing over during meiosis. Crossing over occurs when homologous chromosomes exchange genetic material, resulting in the mixing of alleles between the two chromosomes. This process leads to the creation of new combinations of alleles and contributes to genetic variation in the population.
What is the relationships between chromosomes and homologous chromosomes?
Chromosomes refer to structures with DNA and proteins that contain genetic information. The term "homologous chromosomes" is used to specify that the chromosomes contain the same genes, but have the same or different alleles.
What is the relationship between a gene and an allele?
All chromosomes consist of genes and non coding material. Animals with chromosomes arranged in the double helix pattern have two almost identical genes on the chromosomes opposite from the other. When those two genes in particular are discussed, they are called alleles. Frequently one is expressed and one is not, or one is dominant and the other is not.
