Yes, it is the same. Its output is a genetic map with the right order of genes on the chromosome and their distances from each other measured in M (morgans) or cM (centimorgans), which displays the frequency of recombination between two genes.

What is recombination?
Genetic recombination is the process by which a strand of genetic material (usually DNA; but can also be RNA) is broken and then joined to a different DNA molecule. In eukaryotes recombination commonly occurs during meiosis as chromosomal crossover between paired chromosomes. This process leads to offspring having different combinations of genes from their parents and can produce new chimeric alleles.Genetic recombination is the process by which two DNA molecules exchange genetic information, resulting in the production of a new combination of alleles. In eukaryotes, genetic recombination during meiosis can lead to a novel set of genetic information that can be passed on to progeny. Most recombination is naturally occurring. During meiosis in eukaryotes, genetic recombination involves the pairing of homologous chromosomes. This may be followed by information exchange between the chromosomes. The information exchange may occur without physical exchange (a section of genetic material is copied from one chromosome to another, without the donating chromosome being changed)(see SDSA pathway in Figure); or by the breaking and rejoining of DNAstrands, which forms new molecules of DNA (see DHJ pathway in Figure). Recombination may also occur during mitosis in eukaryotes where it ordinarily involves the two sister chromosomes formed after chromosomal replication. In this case, new combinations of alleles are not produced since the sister chromosomes are usually identical. In meiosis and mitosis, recombination occurs between similar molecules (homologs) of DNA. In meiosis, non-sister homologous chromosomes pair with each other so that recombination characteristically occurs between non-sister homologues. In both meiotic and mitotic cells, recombination between homologous chromosomes is a common mechanism used in DNA repair.Genetic recombination and recombinational DNA repair also occurs in bacteria and archaea.Recombination can be artificially induced in laboratory (in vitro) settings, producing recombinant DNA for purposes including vaccinedevelopment.V(D)J recombination in organisms with an adaptive immune system is a type of site-specific genetic recombination that helps immune cells rapidly diversify to recognize and adapt to new pathogens.
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.
Where does recombination of DNA occur?
Recombination occurs when two molecules of DNA exchange pieces of their genetic material with each other. One of the most notable examples of recombination takes place during meiosis (specifically, during prophase I), when homologous chromosomes line up in pairs and swap segments of DNA
Why do young plants and animal resemble their parents?
When offsprings in a plant are produced by vegetative propagation, these are like their parents only because recombination of genetic material is avoided due to absence of meiosis.
Why is genetic recombination important?
Since it's sexual two organisms give a part of their DNA to put together and so the resulting organism gets some, not all, of the traits from both starting organism. This means that after sexual reproduction the new organism will always be different from others, but have some characteristics that are the same. The new combination of characteristics can either be bad or good and this will determine survival and weather or not the combination will be passed down.
How does a mule compare to an organism with recombination DNA?
Both have genetic material from more than one species
Who were Lederberg and Tatum?
Joshua Lederberg was a molecularbiologist and geneticst. Tatum was also a geneticst. Both were from the USA. Lederberg and Tatum discovered the genetic recombination in bacteria.
What is the other name of homologous recombination?
It's also called "general recombination".Sometimes homologous recombination is mistakenly called "crossover", but crossover is a result of homologous recombination and not really synonymous.
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.

How does genetic recombination cause genetic variation?
In recombination, cross-overs exchange alleles between homologous chromosomes during meiosis in both parents. This is what allows for much of the genetic variation in the offspring of a population in each generation.Sexual recombination works in three different ways. First, chromosomes of the male and female exchange genetic material in the process of crossing over. Secondly, the tetrads in meiosis have two different ways to independently orient themselves in prophase I, And lastly fertilization is a completely random process.

Both EmergencyPrePlans.com and HazmatSoftware.com offer the kind of mapping software you are looking for.
What can cause genetic variation?
genes are kept in chromosomes, there is this thing called meiosis which is when the chromosomes/genes get split in half, one from both parents that way it equals the normal amount of genes later. the genes have tons of ways to mix and match around while getting split apart and then ending up in the same place.
