Linkage occurs between two genes when they are so near (less than 50 for Complete linkage and more than 50 but not more than 100 for Incomplete linkage) that they cannot undergo crossing over during meiosis and thus dont give new type of gametes which later could give recombinant(new type different than parents) character...

What is linkage theory?
Linkage theory proposes that genetic traits are transmitted together because they are located close to each other on the same chromosome. This theory helped to establish the concept of genetic recombination and the understanding of genetic linkage mapping. It was an important development in the field of genetics.
How can one create a linkage map for genetic analysis?
To create a linkage map for genetic analysis, one must first identify genetic markers that are inherited along with the gene of interest. These markers are then used to track the inheritance patterns of the gene through generations. By analyzing the frequency of recombination events between the gene and the markers, the relative positions of the gene and markers on a chromosome can be determined, creating a linkage map.
If two genes are on the same chromosome, how does their proximity affect their inheritance and genetic linkage"?
The closer two genes are on the same chromosome, the more likely they are to be inherited together, a phenomenon known as genetic linkage. This is because the likelihood of the genes being separated during the process of genetic recombination decreases as their proximity increases.
A major deviation from mendels law occurs because of?
A major deviation from Mendel's laws, specifically the law of independent assortment, can occur due to genetic linkage. This is when genes located close together on the same chromosome are inherited together more often than expected. As a result, they do not assort independently as predicted by Mendel.
What is a Linkage map?
An association between two or more genes such that the traits they control tend to be inherited together.Or more simply:A genetic map based on recombination frequencies.
What is memory linkage?
what is a linkage linkage happens when a particular genetic loci or allele for genes are inherited jointly.

What is a genetic map?
Genetic map is a graphic representation of a linkage group in the form of line which shows by points the sequence of the genes and the relative distances between the genes it contains. Genetic map is called a linkage map, or chromosome map.
What is linkage disequilibrium?
Linkage disequilibrium is the non-random association of alleles at two or more loci. It is broken down by recombination. Linkage equilibrium = independence between allele frequencies at two different SNPs Linkage disequilibrium = Association between alleles at different SNPs (SNPs are Single Nucleotide Polymorphism - Pronounced snips)

Compare a linkage map and a sequencing map?
A linkage map is a genetic map that shows the relative positions of genetic loci on a chromosome based on recombination frequencies, while a sequencing map provides the exact order and position of nucleotides in a DNA sequence. Linkage maps are based on genetic distance, whereas sequencing maps provide physical distance information. Linkage maps are useful for studying genetic inheritance patterns, while sequencing maps are crucial for understanding the actual genetic code.

X-linkage was discovered for the first time in?
Genetic linkage was first discovered by the British geneticists William Bateson and Reginald Punnett shortly after Mendel's laws were rediscovered. The understanding of genetic linkage was expanded by the work of Thomas Hunt Morgan. Morgan's observation that the amount of crossing over between linked genes differs led to the idea that crossover frequency might indicate the distance separating genes on the chromosome. Alfred Sturtevant, a student of Morgan's, first developed genetic maps, also known as linkage maps.
Which term defines the distance between two genes on a single chromosomes?
The term that defines the distance between two genes on a single chromosome is "genetic linkage." This distance is measured in units called centimorgans, and genetic linkage helps scientists understand how close or far apart genes are from each other on a chromosome.
What is a Linkage map?
An association between two or more genes such that the traits they control tend to be inherited together.Or more simply:A genetic map based on recombination frequencies.
