Answer:
Genes lying close to each other on chromosome
Explanation:
When genes lie close to each other on chromosome, they are inherited together as an intact unit in meiosis cell division and such genes are termed as linked genes.During meiosis the genetic material (allele/genes) is exchanged between the homologous parent chromosome which causes chromosome recombination and thus the formation of linkages These genes have high chances of recombination as they lie close to each other.
