||"[Researchers] sequenced the genomes of five individuals derived by 30 generations of single-seed descent from the reference strain Col-0 (4),
for which a high-quality genome was published in 2000 (5)."
||"Deletions larger than 3bp occurred at a frequency of 0.5×10^-9±0.2×10^-9 per site per generation and removed on average 800±1900 bp per event [BNID 110372]." (note how the distribution is so wide that the standard deviation is larger than the mean-Ron Milo)
