Select the correct statement from the ones give below with respect to dihybrid cross.

Options

(a) Tightly linked genes one 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:

Tightly linked genes on the same chromosome show very few recombinations

Explanation:

Linkage is the inheritance of genes of same chromosome together and capacity of these genes to retain their parental combination in subsequent genration. The strength of linkage between two genes is inversely proportional to the distance between the two. This means, two linked genes show higher frequency of recombination if the distance between them is higher and lower frequency if the distance is smaller.
