front 1 heredity | back 1 the process by which traits are passed from parents to offspring |
front 2 pure | back 2 offspring is same breed, certain traits will appear over and over again |
front 3 hybrid | back 3 offspring that carry unlike traits from each parent |
front 4 generation | back 4 all offspring produced by a set of parents; a type of timeline people are called |
