Question

Gametic maps of chromosomes are based on

• A. Non disunction
• B. Tranlocation
• C. Dominance
• D. Genetic recombination
• E. Chromosomal aberrations.

Answer 1

The correct option is D Genetic recombination

A linkage or genetic chromosome map is a linear graphic representation of the sequence and relative distance of the various things present in a chromosome. A chromosome app is also called a linkage map or the genetic map. The percent of crossing over between two genes is directly proportional to the distance. The unit of crossing over has been termed as centiMorgan.

So, the correct option is 'Genetic recombination'.
