Detailed explanation-1: -When genes are close together on the same chromosome, they are said to be linked. That means the alleles, or gene versions, already together on one chromosome will be inherited as a unit more frequently than not.

Detailed explanation-2: -During meiosis, chromosomes are recombined, resulting in gene swaps between homologous chromosomes. If genes are close together, the chances of being recombined are higher than if they are far away from each other. It is impossible for linked genes to be on different chromosomes.

Detailed explanation-3: -Genes that are located on the same chromosome are called linked genes. Linkage explains why certain characteristics are frequently inherited together.

Detailed explanation-4: -Unlinked genes are present on separate chromosomes. They are inherited together and follow Mendel’s law of independent assortment. These genes can also be on the same chromosome, but far away from each other.

Detailed explanation-5: -Explain why two genes found on the same chromosome are not always linked forever. Crossing-over during meiosis sometimes separates genes that had been on the same chromosome onto homologous chromosomes. 6. The new combinations of alleles produced by crossover events help to generate genetic .
