A testcross involves breeding an organism with an unknown genotype with a homozygous recessive individual to determine the unknown genotype, using offspring phenotype ratios to reveal it.
Un croisment de test consiste à croiser un organisme avec un génotype inconnu avec un individu homozygote récessif pour déterminer le génotype inconnu, les ratios phénotypiques des descendants révélant ce dernier.
