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: -It follows that: • the probability of a crossover between two genes is proportional to the distance between the two genes. That is, the greater the distance between the two genes, the greater the probability that a crossover will occur between them during meiosis.

Detailed explanation-3: -Explanation: There are certain sites on DNA, which have a high probability of crossing over called hot spots and those sites which have a low probability of crossing over are called cold spots.

Detailed explanation-4: -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-5: -The closer two genes were to one another on a chromosome, the greater their chance of being inherited together. In contrast, genes located farther away from one another on the same chromosome were more likely to be separated during recombination.
