  4. Which is true about a testcross? A.) It is mating between two hybrid individualsB.) It is mating between a hybrid individual and a homozygous recessive individualC.) It is a mating between a homozygous dominant individual and a homozygous recessive individualD.) It is mating to determine which individual is homozygous recessive E.) It is a mating between an individual of unknown genotype and a homozygous recessive individual

  5. E. It is a mating between an individual of unknown genotype and a homozygous recessive individual
