Thank you for the opportunity to help you with your question!

1.  All linked alleles would remain linked indefinitely - no chance of them assorting independently. 

 
2.  This would limit the phenotypic diversity in a population. 
 
3.  A beneficial allele on the same chromosome as a deleterious allele would have essentially no chance of ever being inherited separately;  natural selection would always occur on all the alleles that had to be inherited together together

Please let me know if you need any clarification. I'm always happy to answer your questions.
