Select the correct statement from the one's given below with respect to dihybrid cross.Select the correct statement from the one's given below with respect to dihybrid cross.

Options

  1. Atightly linked gene on the same chromosome show higher recombinations
  2. Bgenes for apert on same chromosomes show very few recombination
  3. Cgenes loosely linked on the same chromosomes show similar recombination as lightly linked ones
  4. Dtightly linked genes on the same chromosomes show very few recombination

Correct answer

D. tightly linked genes on the same chromosomes show very few recombination

Step-by-step solution

When two genes are close together on the same chromosome, they do not assort independently and are said to be linked and shows less frequency of recombination. Whereas genes located on different chromosomes assort independently and have a recombination frequency of (50 \%) called as less closely linked genes. So, the correct answer is 'Tightly linked genes on the same chromosome show very few recombinations'. Select the correct statement from the one's given below with respect to dihybrid cross.
