You can still participate for free, the donation is optional as I have mentioned to you in previous forum posts and personal email. We are doing this purely for science, not business in any means.
We noticed that people we frustrated with the wait time, so in order to solve it we came up with Darwin’s Ark a non-profit that would give participants the option to fund their dogs samples since, yes grant money takes time (funding their dogs sample will results in guaranteed sequencing ASAP and therefore receive results much faster).
Science is complicated, expensive and does not happen quickly.
Again, we apologize for your frustrations, but we are doing our very best.
