Homologous and Site-Specific Recombination: Homologous Recombination

Introduction

• Recombination is the process by which fragments of DNA are split up and put back together to create new allele combinations.
• Genetic diversity is created among many creatures as a result of this process. It is also known as genetic reorganization.
• It is described as the process in which genetic material is transferred between various creatures to create children with novel allele combinations that are distinct from those seen in either parent.
• There are two diffe…
