The percentage rof recombination involving th seed shape and seed colour ina plant is 10%. What is the distance (mp) between the genes on a chromosome controlling these characters?

In young's experiment using monochromatic light, the fringe pattern shifts by a certain distance on the screen when a mica sheet of refractive index 1.6 and thickness 2 micron is introduced in the path of one of the interfering waves. The mica sheet is then removed and the distance between the slits and the screen is doubled. It is found that the distance between successive maxima now is the same as the observed fringe shit upon the introduction of the mica sheet. The wavelength of light is
