How does crossing over occur more frequently between genes that are close together on chromosomes?

with some qualification, especially around the centromeres and telomeres, one can say that crossing over is somewhat randomly distributed over the length of the chromosome two loci that are far apart are more likely to have crossover than two loci that are close together.

What is homologous chromosomes frequently exchange portions of their DNA called?
It's called crossing over, and it generally only happens between homologous chromosomes.
What action occurs during meiosis exchanging pieces of chromosomes between homologous chromosomes?
crossing over
What is the exchange of a corresponding segment between homologous chromosomes?
It would appear you are speaking of crossing over which takes place in Prophase I of meiosis.
What happens chromosomes undergo crossing-over?
During meiosis, permutation.
What is the exchange of DNA between homologous chromosomes during pro phase of meiosis?
Crossing over or chromosomal crossover.
What is homologous chromosomes frequently exchange portions of their DNA called?
It's called crossing over, and it generally only happens between homologous chromosomes.
What is the exchange of genes between homologous pairs of chromosomes?
homologous chromosomes exchange alleles during crossing over.
What is the difference between synapsis and crossing over?
-- synapsis: homologous chromosomes are coming close together and bivalents are formed.-- crossing-over: non-sister chromatids of homologous chromosomes interchange genesThe pairing (formation of bivalents) allows crossing over to take place and this enables genetic variations in the gametes.
What action occurs during meiosis exchanging pieces of chromosomes between homologous chromosomes?
crossing over
Crossing-over is the exchange of reciprocal segments of DNA between homologous chromosomes true or false?
It's true that crossing over is the exchange of reciprocal DNA parts between homologous chromosomes.
What is the exchange of a corresponding segment between homologous chromosomes?
It would appear you are speaking of crossing over which takes place in Prophase I of meiosis.
What process results in an exchange of genes between homologons chromosomes?
Crossing Over
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.
Compare the process of crossing-over and independent assortment?
Crossing over is the exchange of DNA between homologous chromosomes where as Independent assortment is the process in which the chromosomes pair align themselves at the equator of the cell.
The exchange of parts between non homologous chromosomes...?
Crossing Over
What happens chromosomes undergo crossing-over?
During meiosis, permutation.
What exchange of genetic material between arms of homologous chromosomes?
When chromosomes cross over. (Chromal Crossover, I believe)
