Harry Potter - Purebloods?

Question

I have something that confuses me here .... It's little weird ;]

Harry is a half blood and Ginny is a pure blood ... Their kids are halfbloods .... How a wizarding family can become a pureblood family?

Potters once were purebloods , of course , until James married Lily and they had Harry , who is a halfblood because of his mother.

Is this possible or not ?

xx :D

Answer 1

Ginnys and Harrys children are not half blood but pure blood coz both of their parents were wizards. Harry was a half blood coz his mother was from a  Muggle Family.If both the parents are wizards then its  apure blood but if one of the parents has their parents as muggles then that makes their children a half blood.

Answer 2

I guess its like in genetics. the dominant blood side takes control of recessive blood side. so pure blood then i guess will be dominant.

Answer 3

wait so.. shouldnt there be the concept of.. quarter blood.. then?.. lol..
