The correct answer is: Tightly linked genes on the same chromosome show very few recombinations
Recombination is a rearrangement of genes during meiosis so that a gamete contains a haploid genotype with a new gene combination. 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).
