testcross

• Генетическое скрещивание между организмом с неизвестным генотипом по определённому признаку и организмом, гомозиготным по рецессивному аллелю этого признака, используемое для определения неизвестного генотипа по полученному потомству.

A genetic cross between an organism with an unknown genotype for a specific trait and one that is homozygous recessive for that trait, used to determine the unknown genotype from the resulting offspring.
