Q. Genetic map is one that

AIPMTAIPMT 2003Principles of Inheritance and Variation

Solution:

Linkage map is a graphic representation of relative positions/order and relative distance of genes in a chromosome in the form of line like a linear road map depicting different places and their relative distances without giving exact mileage. It is based on Morgan's hypothesis (1911) that frequency of crossing over/recombination between two linked genes is directly proportional to the physical distance between the two. 1 map unit or centimorgan is equivalent to 1% recombination between two genes.
