Q. Select the correct statement from the ones given below with respect to dihybrid cross.
A) Tightly linked genes on the same chromosome show higher recombinations
B) Genes far apart on the same chromosome show very few recombinations
C) Genes loosely linked on the same chromosome show similar recombinations as the tightly linked ones
D) Tightly linked genes on the same chromosome show very few recombinations
Explanation
Morgan and his group found that when genes were grouped on the same chromosome, some genes were very tightly linked (showed very low recombination), while others were loosely linked (showed higher recombination).
