    • ‘In some sense, every model organism needs to be developed and selected from its natural progenitors, and no organism will be an entirely ideal model.’
    • ‘The comparison of newly formed polyploids with their haploid progenitors has revealed that nascent polyploids have a defect in stationary-phase viability.’
    • ‘There is, however, evidence of genome downsizing in polyploids relative to their diploid progenitors in some cases.’
    • ‘The results from these studies are generally consistent with theoretical expectations of higher genetic diversity in tetraploids than their diploid progenitors.’
    • ‘Boxes represent extant groups and their ancestral progenitors.’
    • ‘More significantly, this less-than-proportional increase in genome size in a polyploid species expected from the addition of its diploid progenitors appeared to be a widespread phenomenon in flowering plants.’
    • ‘For example, the unicellular progenitors of plants underwent an important evolutionary step following the establishment of a second endosymbiotic relationship, resulting in the evolution of the plastid.’
    • ‘Wolfe offers an updated understanding of fraternities as social lockboxes far removed from their bawdy Animal House progenitors.’
    • ‘We examined the segments of repeats of 16 strains, each descended from different wild progenitors.’
    • ‘Currently, six major tetraploid races are recognized and their diploid progenitors have been identified.’
    • ‘The domestication of plants from their wild progenitors has led to the production of a wide variety of crops that share a number of traits.’
    • ‘Indeed, some genes originating from different progenitors are expressed in specific tissues or at different developmental stages, as demonstrated in cotton.’
    • ‘The result is premature apoptosis (programmed cell death) of progenitors and failure of stem cells to mature and differentiate.’
