Genetic map of chromosome are based on

Options

(a) non-disjunction
(b) translocation
(c) dominance
(d) genetic recombination

Correct Answer:

genetic recombination

Explanation:

Genetic chromosome map is a linear graphic representation of the sequence and relative distance of the various genes present in a chromosome. Two genes which have the maximum distance between them on the chromosome will have the maximum percentage of crossing over or recombination. So relative distance between genes is indicated by the percentage of their recombination.
