Multiple heterosis

{
  "id": "MLC-T-CHM-007657",
  "term": "Multiple heterosis",
  "field": "Chemistry",
  "definition": "The summed fitness gain of an individual that is heterozygous at several loci, each locus contributing heterozygote superiority (overdominance), so that the separate effects add up to a higher overall fitness. It differs from single-locus heterosis, where one heterozygous locus raises fitness, because many loci act together in population genetics.",
