Crossover Interference

Crossover interference is an effect that occurs when two alleles, one inherited from each parent, interfere with one another. This can result in a change in the phenotype of a trait that is not observed when either allele is inherited alone. Crossover interference is a fundamental property of genetics, and occurs in many organisms, including humans. Its significance lies in our understanding of how traits are passed down through generations. It also has implications for medical research, as it can be used to study the effects of alleles on diseases, as well as to inform decisions on genetic counseling.
