Will imputation help or hinder?

DNA testing for genealogy is at risk. Only Family Tree DNA has resisted using the newest chip offered by Illumina, the only viable company making such chips for autosomal testing.


The new chip is comparable to the old in only 20% of coverage! The companies using it are now forced to apply “imputation”, a means of inferring results. I find that shocking and a severe blow to the efficacy of genetic genealogy.  For a detailed discussion, see  https://dna-explained.com/2017/09/05/concepts-imputation/
