   “1944 June 21, James A. G.

   “This plan takes advantage of the fact that barless is the most recessive of a series of alleles.”

   “The series of murine Agouti alleles is a consistent array as it progresses from the most recessive to the most dominant allele (Jackson, 1994).”

   “The worker–client relationship is more recessive and has a more catalytic and enabling quality.”

noun

1. A gene that is recessive.

   “Suppose, for example, that we started with a population consisting of pure dominants, heterozygotes, and recessives in the ratio 1 : 4 : 4.”

   “Finally, if we suppose provisionally that the mutant genes are dominant just as often as they are recessive, selection will be far more severe in eliminating the disadvantageous dominants than in eliminating the disadvantageous recessives.”

   “Selection favoring recessives is common in maize breeding for several traits, such as sweetness, opacity, brachysm, lack of ligules.”
