It means that there were two recombinations between the markers; so it appears in the phenotype to be the same as no recombination.

Is recombination mapping and genetic mapping both means same?
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 the difference between Holiday model and double strand break model of recombination?
In 1964, Robin Holliday proposed a model that accounted for heteroduplex formation and gene conversion during recombination. Although it has been supplanted by the double-strand break model (at least for recombination in yeast and higher organisms), it is a useful place to start.
How does crossing over make gene mapping possible?
When genes are on the same chromosome but very far apart, they assort independently due to crossing over (homologous recombination). This is a process that happens at the very beginning of meiosis, in which homologous chromosomes randomly exchange matching fragments.
How do you find recombination frequencies on a chromosome?
Recombination frequency = (Recombinant offspring) / (Total offspring) i.e. the recombination frequency is calculated by taking the number of recombinant offspring and dividing it by the total number of offspring.
What are the 3 sources of genetic recombination?
Genetic recombination refers to the process by which two DNA molecules exchange genetic information. The three types of genetic recombination are crossing over, conservative site-specific recombination and transpositional recombination.

What are types of mapping?
bump mapping data mapping texture mapping displacement mapping relief mapping parallax mapping
What is inhereited variation with recombination and gene flow?
What is inertied variation with recombination .
What are map types?

What is a recombination breakpoint?
A breakpoint is defined as the location where a recombination event occurs in a sequence.
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 is direct mapping and mapping function?
it means mapping directly
An example sentence using the word recombination in it?
The word "recombination" is a noun. An example of a sentence using the word would be: She understood that DNA recombination involved the exchange of genetic material.
What is it called when you are removing a section of DNA to be used for recombination?
Removing a section of DNA to be used for recombination is called
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.
