    • Within both groups, many plants possessed a genome content that deviated from the euploid parents by at least the approximate size of one chromosome.
    • Aneuploid pollen grains compete poorly with euploid pollen and so aneuploidies are eliminated when propagated through the male.

Derivatives

  • euploidy

  • noun
    Genetics
    • To obtain a more precise determination of genome size in some of these lines, multiple individuals from a few of the lines with genome content values furthest from euploidy were grown and their genome size was determined.
      Example sentencesExamples
      • Although trisomic plants segregate for only two genetic conditions, euploidy and hyperploidy, the system is simpler to use than B-A translocations.
