Frequency of recombination between gene pairs on same chromosome as a measure of the distance between genes to map their position on chromosome, was used for the first time by
Henking
Thomas Hunt Morgan
Sutton and Boveri
Alfred Sturtevant
The chromosome maps are not accurate maps because
Crossing over causes
The map distance between genes $A$ and $B$ is $3$ units, between $B$ and $C$ $10$ units and between $C$ and $A$ $7$ units. The order of the genes in a linkage map constructed on the above data would perhaps be
In Mendelism, linkage was not observed due to
In order to calculate map distance of genes on a chromosome, one must know the
