Answer:
A mutation could be passed on to an offspring by inheritance.
Explanation:
These 4 scenarios that can occur are autosomal dominant, autosomal recessive, x-linked dominant and x-linked recessive. Autosomal dominant is when both parents have the disorder and pass it on to one of their children but not the other. This means that both parents are heterozygous. Heterozygous is a when a gene has one dominant allele and one recessive allele. Autosomal recessive is when both parents don’t have the disorder but one of their offspring do. This also means that both parents are heterozygous. Next is X-Linked dominant. This can occur when one of your grandparents has the disorder and passes it on to your dad and as a result all of his daughters are affected. Lastly, X-Linked Recessive is similar but it’s the mother that gets the disorder and passes it on to her sons. This process can really help determine whether or not your child has a disorder and is completely healthy.

No one knows exactly when viruses emerged or from where they came, since viruses do not leave historical footprints such as fossils. Modern viruses are thought to be a mosaic of bits and pieces of nucleic acids picked up from various sources along their respective evolutionary paths. Viruses are acellular, parasitic entities that are not classified within any domain because they are not considered alive. They have no plasma membrane, internal organelles, or metabolic processes, and they do not divide. Instead, they infect a host cell and use the host’s replication processes to produce progeny virus particles. Viruses infect all forms of organisms including bacteria, archaea, fungi, plants, and animals. Living things grow, metabolize, and reproduce. Viruses replicate, but to do so, they are entirely dependent on their host cells. They do not metabolize or grow, but are assembled in their mature form.
Viruses are diverse. They vary in their structure, their replication methods, and in their target hosts or even host cells. While most biological diversity can be understood through evolutionary history, such as how species have adapted to conditions and environments, much about virus origins and evolution remains unknown.
