Why is the most likely num. of gens to MRCA 35, with that likelihood
being 2%, while there is a 25% likelihood of MCRA at fewer (30) gens? I
would think the higher likelihood of the two would be the greater (35)
generations. I clearly don't get the terminology.

Number of loci compared
25

Number of loci matched
21

Most likely num. generations separating you from your paternal MRCA
35

Maximum Likelihood Estimation (MLE) at 35 generations
0.022

Num. generations at which cumulative likelihood reaches 25%
30

Num. generations at which cumulative likelihood reaches 50% (Median)
41

Num. generations at which cumulative likelihood reaches 75%
55
