回答: When does Gene mutation occur? 由 HunHunSheng 于 2005-3-18, 12:02:04:

I thought I shouldn’t answer until real experts jump in. They didn’t show up.
There are mainly two types, one is point mutation and the other is segment mutation.
Point mutation happens at anytime and segment mutation only occurs when a gene is duplicating itself.
