What happens to "filial mitzvot" (e.g., filial respect/kibud av v'em, mourning/aveilut, being fruitful/pru u'rvu but also more broadly) when a parent and their child both convert?
Practically, imagine a person converting and a year later his father/mother also convert. Does that person "regain" an obligation to honor and mourn his newly Jewish parent? Do the Jewish children of the converted parent count as children from a pria v'rvia perspective?
Are there general rules or is it specific for each commandment?
