What can experienced hybridizers, or experienced keepers of many hybrids, tell me about the heritability of fragrance please?

For example, a Vanda Mimi Palmer that I sniffed in Singapore had an outstanding fragrance. Stopped me in my tracks. I have not been able to find this cultivar, but have found several hybrids for which it is a parent. What are the chances of its fragrance, in all its glory, being passed down?

Happy to learn anything else about fragrance inheritance too...

Thanks
