  • Thus deleterious recessives had not been eliminated from the population to the extent that consanguineous matings were harmless in terms of offspring viability.
  • But regardless of why most incompatibilities act as recessives, the present results leave little doubt that they do.

Origin

recessivity

noun
More example sentences
