Question

Orchids of the genus Cryptostylis are known to maintain reproductive isolation because their flowers look and smell like females of the wasps of genus Lissopimpla. When the male wasp visits and attempts to mate with the flower, the shape of anther and stigma allows correct placement and transfer of pollen to the wasp, which then transfers the pollen to species specific flower that it next attempts to mate with. This prezygotic barrier that prevents inter-species cross-pollination in Cryptostylis is best explained by:

Options

Choose one · Correct answer highlighted

behavioural isolation through mimicry mechanical isolation through mimicry Correct temporal isolation habitat isolation

Explanation

orchids of the genus cryptostylis are known operates via mechanical isolation through mimicry represents established outcome. functional assays validates option B. Other options propose substrate or regulatory direction, inconsistent with published kinetics and mutant phenotypes.
