NEET 2010 Biology question

Select the correct statement from the ones given below with respect to dihybrid cross.

(1)Genes far apart on the same chromosomes show very few recombinations
(2)Genes loosely linked on the same chromosome show similar recombinations as the tightly linked ones
(3)Tightly linked genes on the same chromosome show very few recombinationsCorrect
(4)Tightly linked genes on the same chromosomes show higher recombinations

Answer: (3)

Solution

Linked genes lie on the same chromosome; the closer they are, the stronger the linkage and the lower the frequency of crossing over between them. Tightly linked genes therefore show very few recombinations (parental
