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

Text Solution

Verified by Experts

The correct Answer is:
D
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 lossely linked (showed higher recombination). Recombination is a process of rearrangement of genes during meiosis so that a gamete contains a haploid genotype with a new gene combination.
