Q. Select the correct statement from the ones given below with respect to dihybrid cross
A) Tightly linked genes on the same chromosome show very few recombinations
B) Tightly linked genes on the same chromosome show higher recombinations
C) Genes far apart on the same chromosome show very few recombinations
D) Genes loosely linked on the same chromosome show similar recombinations as the tightly linked ones
Explanation
[Solution from source] Morgan found that genes lying close together (tightly linked) rarely separate by crossing over, so they show few recombinants, as with the white-eye and yellow-body genes in Drosophila. Genes far apart or loosely linked show more recombination, not less. Answer (1).
