Sunday has it.
It is like each puppy in a litter has unique genetics that is a combo of the two parents, so does each seed in the seed pod.
For humans, the analogy would be paternal twins (each from their own egg so they can even be one male and one female)
Daylilies had three chambers but each contains several seeds. There should the same random genetic combo of the parents in each seed regardless of if they are in the same ovary.
Food for thought - just like dogs or cats can mate with more than one male and have pups/kittens in the litter from different fathers. Open pollinated daylilies can too!
Especially if they are bee polinated as the bee can be leaving grains of pollen from several different flowers it visited previously.
