[i] ^aIncludes genes not assigned to families due to failure to cluster (3521 of total and 1096 of CNV genes) and genes assigned to families that lack membership of rice, sorghum, or Arabidopsis (1017 of total and 392 of CNV genes). Deviation from expected values were highly significant (P < 0.0001) for all CNV classes based on χ² tests.

[ii] ^bDeviation from expected family size distributions were highly significant (P < 0.0001) for all CNV classes except for CNV (Both), which yielded a significant P-value of 0.0241.
