Detailed explanation-1: -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-2: -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-3: -Linked genes sit close together on a chromosome, making them likely to be inherited together (left). Genes on separate chromosomes are never linked (center).
Detailed explanation-4: -Genes that are located on the same chromosome are called linked genes. Alleles for these genes tend to segregate together during meiosis unless they are separated by crossing over. Crossing over occurs when two homologous chromosomes exchange genetic material during meiosis I.
