The closer genes are to each other on a chromosome, the less likely they are to be separated due to crossing over. This is because crossing over occurs between homologous chromosomes during meiosis and involves the exchange of genetic material between non-sister chromatids. The closer two genes are to each other on a chromosome, the less physical distance there is between them and the less likely they are to be separated during this process.
