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.

What results from the process of crossing over during prophase 1?
It results in the exchange of alleles between homologous chromosomes and produces new combination's of alleles.
How does meiosis contribute to genetic recombination?
Meiosis is involved in sexual reproduction. It produces gametes (eg. sperm and ovum/egg) which contain half the number of chromosomes of a normal (somatic/non-sex) cell. This means that in order to produce a new organism the gametes from the two different parents must combine. This results in an organism with a combination of the parents' genes (half the chromosomes from one parent, and half from the other). The organism is therefore different to both parents.
How does meiosis introduce genetic variation in to offspring?
Meiosis produces gametes which then go on to participate in sexual reproduction. Sexual reproduction combines the genetic material of the two parents - therefore creating variation.
The main results of meiosis?
Meiosis is a process of reduction division in which the number of chromosomes per cell is cut in half through the separation of homologous chromosomes in a diploid cell.
What happens in the tetrad stage?
During the tetrad stage, the metaphase I of meiosis starts to happen. When this occurs, the diploid meiocyte divides twice.
What results form the process of crossing-over during prophase 1?
I do GP Biology (9th year here), and I'm on the quiz "Week 13-Meiosis: The Life Cycle of S-x Cells". I got the question What happens during crossing over? The answer was "homologous chromosomes trades pieces of DNA." Hope this was the answer you're looking for!
What process produces genetic diversity through random distribution of chromosomes?
The random distribution of homologous chromosomes during meiosis is called independent assortment
What results from the process of crossing over during prophase 1?
It results in the exchange of alleles between homologous chromosomes and produces new combination's of alleles.
What is the genetic makeup of the final product of mitosis?
Mitosis produces two genetically identical daughter cells which are diploid (2n), meaning that they have two sets of homologous chromosomes (chromosomes with genes for the same characteristics).
How does meiosis contribute to genetic recombination?
Meiosis is involved in sexual reproduction. It produces gametes (eg. sperm and ovum/egg) which contain half the number of chromosomes of a normal (somatic/non-sex) cell.

This results in an organism with a combination of the parents' genes (half the chromosomes from one parent, and half from the other). The organism is therefore different to both parents.
How does homologous recombination differ from crossing over?
There does not seem to be much difference. Recombination introduces genetic diversity. Single Crossing over results in genetic recombination. Double crossovers may or may not result in genetic recombination.

What happens in the tetrad stage?
During the tetrad stage, the metaphase I of meiosis starts to happen. When this occurs, the diploid meiocyte divides twice.
What produces cell with half the normal number of chromosomes?
the answer is MEIOSIS meiosis produces 4 single cells with half member of the chromosomes mitosis produces 2 cells with full member of the chromosomes
Characteristics of meiosis include?
Meiosis is a type of sexual reproduction in which the number of chromosomes are reduced by half by means of separation of homologous chromosomes, producing 2 haploid cells whereas Mitosis is a process of asexual reproduction in which a single cell divides into two producing two similar cells with equal number of chromosomes resulting in 2 diploid cells. Meiosis produces female egg cells or male sperm cells. Mitosis produces all cells other than sex cells.
How is the chromosomes in the eukaryotes different from the structer of chromosomes in prokaryotes?
in eukaryotic chromosomes it produces DNA to live and in prokaryotic chromosomes it is nothing but bacteria.
