Unlikely based on the paper (assuming you mean "randomly mutated"):
- The reversion frequency (10%) was much higher than random mutation would allow.
- Non-revertant random mutations did not appear in the sequenced alleles above expected background.
- Perhaps most importantly - the revertants always had the same exact polymorphisms that were present in their "grandparents'", but not "parents'", genome.
good point.
take note. in at least animals (i'm a zoo nut not a botanist) the germ cells to be used to make the various sex cells are formed while a specimen is still an embryo--quite early on at that. so. your children are really your parents' children. sort of. it's kind of complicated.
