Aperson that is a carrier has what combination of alleles?

Carriers usually have the recessive versions of the allele . That means that they could be Healthy but Carriers -Gg- ( assume G is an allele for a specific protein ) or they could be unhealthy , yet still being carriers -gg-

Alright, i'm gonna try to explain this as good as possible. the law of conservation is like a collection overtime. it never changes though. no matter how you change the constituent parts.
