Dear all,
Related to this colour changes i will like to put forth one thought.
According to me it the somatic mutation. Mutations are the one which appear suddenly without any clue in previous generation.
If these mutations occur in gametes then they carried forward in future generations but if thy occur in somatic cells then are seen in only those organisms.
If some changes occur while the flower bud is getting formed, part of the flower gets the chromosomes with genes producing the original colour say white, while other portion may get the chromosomes with genes producing pink colour. When the flower opens the colours will be seen accordingly as partly pink and partly white.
Since this is somatic mutation it will not be passed on further, and ends with that flower.
In cross fertilization if the pollen grain from plant bearing yellow flower, fertilizes the ovule from the plant bearing magenta flower we may get the flower with yellow and magenta colour. This is very commonly seen in 4 o clock plant Mirabilis jalapa. You can see many many mixtures of colour shades.
In animals if this happens we sometimes get gynandromorphs, where half side will be male and half female.
For example in clover butterflies female has white colour wings and male yellow colour. In gynander we can see white wings on one side of the body and yellow on other. of course this is the example of chromosomal abberation.
This phenomenon is known as moseisisum.
Experts please varify.
