What is duplicate gene action?
The process by which genes are deleted from a chromosome.
The process by which duplicated genes work together to produce a trait.
The process by which genes are duplicated on different chromosomes.
The process by which genes are replicated within a chromosome.
Duplicate gene action refers to the process by which duplicated genes work together to produce a particular trait. This can occur through gene duplication events, in which a new copy of a gene is created on the same chromosome or on a different chromosome. The presence of multiple copies of the same gene allows for redundancy and specialization, increasing the efficiency of the gene and providing a backup in case of mutation or loss. This process can contribute to the evolution of new traits or functions, leading to increased complexity and diversity in the phenotype of an organism.
Option b is the correct answer.
