Why has the diploid genome been an advantage in studying the development of arabidopsis?

#Unit 5. Developmental Biology

It is assumed that polyploidy plants use developmental mechanisms that are unlike those of animals, whereas the developmental mechanisms used by arabidopsis are identical to those of animals, since both are diploid
The diploid genome of arabidopsis provides a marker for the arabidopsis cells in chimeras made with other plants
The diploid genome allows genetic analysis of development, in a manner analogous to the genetic analysis that has been done with Drosophila
The development of polyploid plants is too variable to be of any use in studies of development
