To select organisms for studying the inheritance of traits, the following criteria should be considered: ### Step-by-Step Solution: 1. **Short Lifespan**: - The organism should have a short lifespan. This allows researchers to observe multiple generations in a relatively short period, facilitating the study of inheritance patterns over time. 2. **High Progeny Count**: ...

Fill in the blanks: The tendency of certain traits of two characters to be inherited together generation after generation is called __.
