Should be. Probably a nanner at the end that selfed the bud site. You have a higher chance at a freak from the s2 seed and with no male a higher chance of a bad recessive gene being highlighted in the s2 plant. But yes they will grow if the seeds had a chance to mature before the plant was cut down. They can be almost like a clone from seed or a total bust.
Id include them with other seeds just in case. I have had the best strain ever for me produce seeds without a male in the room. tons of seeds and the only possible male was killed off by week2 flower well before ready to produce pollen.
Without male plants the seed came from a male flower on one of your females. The resulting seeds will be female. If the plant was pollinated by itself it will be an s1. If pollinated by another strain it will be a female cross of the 2.
If the genetics hermied due to environment, there is no increased chance of hermaphrodite plants in the seed.
If the genetics had the Hermie trait regardless then you have the same chance as you did with the original seed of producing male flowers.
