potential legal conflict due to confused relationships
Affects on family relationships, and genetic elements in confusion. This could be a cause for legal wrangling on inheritance issues. e.g. genetic mother has acted as nominal grandmother. birth mother is is genetic sibling etc. see also future issues and cloning for some exploration of this issue.
 
Should genetic predisposition be a genuine plea for reduced punishments?

Up to this point the developing cells are undifferentiated and totipotent (each cell can develop into a full humna being and it is at this stage that the separation of the ball of cells into parts produces monozygotic twins. (a natrually occuring process). At about this age the cells change and a line develops in the blastula which is the beginnins of a spinal chord. At this point parliament decided that human development has replaced simple cell replication.
