1.	Double crossovers can involve two, three or four strands at a time. What will be the resultant percentage of recombined genes to normal genes in between which recombination occurred, taking all three types in consideration?(a) 0%(b) 50%(c) 70%(d) 90%I got this question at a job interview.I need to ask this question from Linkage and Crossing Over topic in portion Genetic Recombination of Cytogenetics
Answer» Right choice is (B) 50% Explanation: Taking all types of a DOUBLE CROSS over in CONSIDERATION only 50% of the resultant will show recombination between the genes which are located on two sides of these recombination events.
