      genotype of the litter.
    </dd>
    <dt><code>Mother</code></dt><dd>
      genotype of the foster mother.
    </dd>
    <dt><code>Wt</code></dt><dd>
      Litter average weight gain of the litter, in grams at age 28 days.
      (The source states that the within-litter variability is negligible.)
