Fisher's principle
WebJun 21, 2024 · The Karl Fischer Titration is based on an iodine / iodide reaction: The water reacts with iodine. The endpoint of the titration is reached when all the water is consumed The process uses an organic base (B), sulphur dioxide, iodine and an alcohol. The original Karl Fischer method used pyridine as organic base and methanol as alcohol. WebFisher’s principle assumes that variation in environmental con ditions affects the fitness of sons and daughters equally. If this is not the case, then individuals can be selected to adjust the sex of their offspring in response to the environment. This idea was first applied to explain sex-ratio patterns in
