Select the correct statement from the ones given below with respect to dihybrid cross:
Tightly linked genes on the same chromosome show higher recombinations
Genes far apart, on the same chromosome, show very few recombinations
Genes loosely linked, on the same chromosome, show similar recombinations as the tightly linked ones
Tightly linked genes on the same chromosome show very few recombinations
, Morgan's experiments on Drosophila revealed that when genes are grouped on the same chromosome, their physical association (linkage) varies. Genes that are tightly linked show very low recombination (e.g., 1.3% for yellow and white genes), whereas genes that are loosely linked show higher recombination (e.g., 37.2% for white and miniature wing genes) .
