Genetic Recombination
Recombination is crucial to this process because it allows genes to be reassorted into diverse combinations. Genetic recombination is the process of combining genetic components from two different origins into a single unit. In prokaryotes, genetic recombination takes place by the unilateral transfer of deoxyribonucleic acid. It includes transduction, transformation, and conjugation. The genetic exchange occurring between homologous deoxyribonucleic acid sequences (DNA) from two different sources is termed general recombination. For this to happen, an identical sequence of the two recombining molecules is required. The process of genetic exchange which occurs in eukaryotes during sexual reproduction such as meiosis is an example of this type of genetic recombination.
Microbial Genetics
Genes are the functional units of heredity. They transfer characteristic information from parents to the offspring.

Introduction
One gene/allele can affect the inheritance pattern of other gene present nearby on the same chromosome as Genes can be linked or autonomous/Un-linked. When the genes/alleles segregate during the formation of gametes, those genes are known as autonomous or Unlinked genes while if one gene influence the inheritance pattern of other gene present in a close proximity on the same chromosome then these genes are called as Linked genes and phenomenon is referred as Linkage.
Linkage can be of two types:
- Coupling: when the linkage occurs either between two dominant alleles or two recessive allele.
- Repulsion: when the linkage occurs between dominant and recessive alleles.
