wild carrot genetics?

Dear all,

yesterday I was walking on a dike and one moment I saw a wild carrot
plant. The funny thing was: the flowers were both white and pink (So
inside one flower there were differences). I'm very much interested in
what is happening here; if it is genetical, wouldn't all the flowers
have the same colour? Does anyone have a clue?
Thanks already,

Arnaud

It's not all that rare for plants to bear flowers of two different
colours.

Quite a number of composites have tubular (disc) florets of a different
colour to the ligulate (ray) florets.

In many Hydrangeas the fertile flowers have a different colour from the
sterile flowers.

Daucas carota is not the only umbellifer to bear flowers of two colours
in an inflorescence. (What I've noticed in Daucas carota is one single
pink flower in the centre of an umbel.)

In the same way as successive whorls of a flower differentiate into
different organs (e.g. bracteoles, sepals, petals, stamens and pistils),
different parts of an inflorescence or capitulum can differentiate into
different types of flowers. For example, in peloric foxgloves the apical
flower is actinomorphic, constrasting to the zygomorphic flowers of the
remainder of the inflorescence. More commonly some combination of
sterile, male, female and hermaphrodite flowers are distributed into
different regions of an inflorescence.

If its so funny, why isn't anybody laughing?

Maybe you are just easily amused?

You should not observe lint. The mystery of its existence may completely
overwhelm you.
