Identical P-Values at end of run

[jeremysutherland]

The gwas produces identical p-values at the end of my run(s).

GEMMA 0.98.3 (2020-11-28) by Xiang Zhou and team (C) 2012-2020

mdtr_1 = Plink binary ped file format
host_selectivity.fam = mean traits for replicated genotypes sorted to match genotype file.
"-gk 2" for standardized matrix,
“-km 2” to accompany PLINK binary ped format
"-miss 0.1" adjusts missingness threshold
"-o" output k matrix

Screenshots
P-value tails occur regardless of whether I run the analysis on the whole genome or on chroms individually.
This was run on all 8 chromosomes.

Thinking it might have been an memory issue, this was run on each chromosome individually:
