DNA help

Gabriella • Mommy to Elijah James💙👶🏽

Has anyone done a DNA test with the child and the alleged fathers mom? My child’s father refused to take a DNA test after I already purchased it so his mom agreed to taking it. On the envelope she checked the alleged father box. Will the results still come back 99.9999 or will it be like 50%?? Has anyone done this ? Help pls
