Flower Color Patterns

Copyright 1998-2017 Yoshiaki Yoneda

A portion of flower color patterns was considered to be due to mutable genes in the morning glory. However, recently developed molecular genetic techniques, combined with progress in base arrangement DNA-decoding technology, have begun to elucidate the molecular mechanisms underlying flower color patterns.

9. Blizzard

10. Striped (Blizzard)
