Detailed explanation-1: -In fact, the closer two genes are to one another on a chromosome, the greater their chances are of being inherited together or linked. In contrast, genes located farther away from each other on the same chromosome are more likely to be separated during recombination, the process that recombines DNA during meiosis.

Detailed explanation-2: -If two genes are inherited together more than 50% of the time, this is evidence that they are linked on the same chromosome. The closer together the genes are, the more frequently they will be inherited together.

Detailed explanation-3: -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.

Detailed explanation-4: -Genes that are sufficiently close together on a chromosome will tend to “stick together, ” and the versions (alleles) of those genes that are together on a chromosome will tend to be inherited as a pair more often than not. This phenomenon is called genetic linkage.

Detailed explanation-5: -∙ The more the distance between the gene on chromosomes, then gene shows weak linkage and follow crossing over to form new combination of genetic material and the less the distance between the genes the greater the linkage.
