Which bacterial niche is likely to favor having a large genome?

Question

Quizplus · Accepted Answer

Free-living bacteria are likely to have large genomes because they need to encode a wide range of functions to survive and thrive in diverse environments without the consistent support of a host organism. This contrasts with host-restricted symbionts and pathogens, which often have reduced genomes due to the stable environment and resources provided by their host, leading to the loss of genes unnecessary for survival in that specific niche.
