Why are the genes that produce chemicals inhibiting bacterial growth considered adaptive for fungi?
Fungi and bacteria often compete for the same resources in their shared environments. To gain a competitive advantage, fungi produce chemicals that inhibit bacterial growth, allowing them to have better access to the resources they need. These genes encoding the chemicals provide fungi with a defense mechanism against bacteria, increasing their chances of survival and reproduction. Over time, through natural selection, fungi with these genes are more likely to pass them on to their offspring, leading to an increase in their frequency in the fungal population. Therefore, the genes encoding chemicals that inhibit bacterial growth are considered adaptive for fungi as they enhance their chances of survival and reproduction in their shared environments.
