user16007: Is genetics a kind of meta-tag for inheritance?
If a question is about how genes are passed to child, could I add both tags? If not, should inheritance be preferred each time it applies?
But when does it apply?
Is inheritance specific to the next generation?
To sum up: What is the usage for those 2 tags.

user3340: I have merged questions tagged with inheritance with genetics. 
Also, I have synonymized inheritance with genetics (master tag).
