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
Correct Answer: D
Solution :
[d] Statement in option [d] is correct with respect to dihybrid cross. When two genes are close together on the same chromosome, they do not assort independently and are said to be linked tightly. They show less frequency of recombination. Whereas gene located on different chromosomes assort independently and have a recombination frequency of 50%.
