Where this comes from

Abstract

Scott <i>et al</i> (Reports, 27 November 2020, p. 1086) suggest, on the basis of conclusions obtained from a desert tortoise reintroduction program, that higher genomic heterozygosity should be used to identify individuals for successful translocation. I contend that this recommendation is questionable given these relocated tortoises' unknown origin, their high mortality, insufficient data on resident tortoises and other components of fitness, and potential allelic dropout.
