Question

Question 6 1 pts In light of the previous question, how can we explain the fact that the Hawaiian bobtail squid has clearly evolved to precisely control the association with its bacterial symbiont, whereas the bacterium shows no signs of adapting to the same symbiosis? (Why does the animal host appear to be 'winning the evolutionary race to control their interaction?) symbiotic bacteria are acquired from vast, free-living populations that adapt to their non-symbiotic (free-living) conditions it is actually best for the bacterium to simply let the squid evolve to control everything these particular bacteria have very long generation time (2-3 years) O squid have remarkably high mutation rates

Answer 1

Answer 6:) Second option

There are two theories for the adaptation of squids to their symbiont. First, at a time in the past, a major "duplication event” was occurred in the squid population, which recurrent copies of genes present in the eyes. Second, the enrichment of orphan genes in the accessory nidamental gland presents only in bobtail squid. These findings suggest that bacteria let the squid adapt according to the conditions.

Therefore, the second option is the correct answer.
