Marat540 [252]

Answer:

2.25%.

The recombination progeny occur due to the crossing over of the homologous chromosomes. The linked gene is 30 map units apart and the recombination frequency is 30.

If a plant of Ab/aB is selfed then the progeny obtained is as follows: Ab – parental – 35%, aB – parental – 35%, AB – recombinant – 15%  and ab – recombinant – 15%. The cross between the F2 progeny with aabb is ( 0.15 × 0.15) = 0.0225 or 2.25%.
