Genetic linkage
Genetic linkage is a term that indicates the tendency of inheritance of two nearest gene sequence in a chromosome during meiosis cell division.
Gene linkage is the most important expectation in The law of independent assortment by Gregor Johannes Mandel.
Two genetic marker in a chromosome inheritance probability depends on distance between themselves. this distance is count by centi Morgan.
The nearest gene sequence have highest chance of inheritance and less chance of recombination.
During genetic crossover two physically nearest gene in chromosome is unlikely to seperates into different chromatid during meiosis cell division.
