Sokolowski and Colleagues Showed That Fruit Flies with Either "Rover"or

Sokolowski and colleagues showed that fruit flies with either "rover"or "sitter"behavioural phenotypes were differently selected depending on the crowdedness of the environment. This study provided support for the idea that

A) genetic influence on behaviour is indirect, through physiological structures and processes.
B) sexual reproduction occurs at the level of chromosomes through meiosis.
C) a dominant trait will always succeed in being expressed relative to a recessive trait.
D) genetic diversity favours those species that are willing to adapt.
E) sexual reproduction may increase a species ability to adapt to environmental changes.
