Question restatement: Finish the sentence — Genetic diversity:
Option 1: 'is only useful for breeding if it is in the primary genepool' — This is too narrow. Genetic diversity from beyond the primary genepool and in wild relatives can be valuable for introducing novel traits, not just those within the primary genepool; thus this option undervalues br......Login to view full explanationLog in for full answers
