Detailed explanation-1: -During the process of crossing over genes get rearranged and a new combination will be produced in the gametes. The genes which are placed far apart on a chromosome will have more chance of getting segregated during the process of crossing over when compared to those which are placed closely.

Detailed explanation-2: -The closer together two genes are on a chromosome, the less likely their alleles will be separated by crossing over as shown in the Figure below. Linked genes are inherited together as their alleles are located close to each other and are less likely to be separated by crossing over.

Detailed explanation-3: -Frequency of recombination will be higher. Detailed Answer : Frequency of recombinations will be higher because greater chances of crossing over and also because of the lesser strength of linkage as the strength of the linkage is inversely proportional to the distance between the genes located on the chromosome.

Detailed explanation-4: -Genes that are closer together undergo fewer crossing over events and non-crossover gametes will exceed than the number of crossover gametes. The figure below shows this concept. Finally, for two genes are right next to each other on the chromosome crossing over will be a very rare event.

Detailed explanation-5: -The greater the distance between two genes, the higher the chance that a recombination event will occur between them, and the higher the recombination frequency between them. Crossing over occurs more frequently when genes are farther apart.
