Reiryoku is just latent spiritual power. Reiatsu is the act of "activating" one's reiryoku, increasing its concentration which results in a high pressure. They are not separate entities and should not be referred to as such.

Now then... Yes, reiryoku can be inherited to some degree. We have seen proof of this in that family members carry similar reiatsu signatures, a well over 50% match. However, this is more likely to occur in noble families than common families, due to a strong sense of familial hierarchy. However, at the same time, just like every shonen manga to ever exist, spiritual energy can always be enhanced through training. That goes without saying and should not be overly analyzed; occam's razor is your friend.
