Answer:
the relationships are probably mutual or parasitic
Explanation:
The argument of most scientists when it comes to commensalism is that the likelihood of a relationship between two different organisms, where one of the organisms to be completely unaffected is low. They propose that their relationship, although not obvious, is more likely to be mutualistic or parasitic at best.

Answer:
hey there is no diagram you were supposed to attach it with a document
So the organisms could be classified in the same animal families
Answer:
Horizontal gene transfer
Explanation:
Horizontal gene transfer or lateral gene transfer is when an organisms of different species can acquire a gene from a different one. This process is well understood in bacteria and is responsible for the appearence of antibiotic resistant bacteria. Bacteria can take DNA fragments through a process known as transformation, but this is less common in eukaryotes. Gene transfer agents like viruses could carry the gene from one specimen to the other. Another way could be Horizontal transposon transfer but the exact mechanisms behind it are still under research.
