Final answer:
Testcross (Backcross; concepts of parental, F1, and F2 generations): Testcross or backcross is a breeding experiment used to determine the genotype of an individual possessing a dominant phenotype.
Step-by-step explanation:
Testcross (Backcross; concepts of parental, F1, and F2 generations)
Testcross or backcross is a breeding experiment used to determine the genotype of an individual possessing a dominant phenotype. This experiment involves crossing the individual of interest with a homozygous recessive individual.
The resulting offspring, known as the F1 generation, can provide information about the genotype of the individual being tested. Subsequent crossings of the F1 generation with homozygous recessive individuals result in the F2 generation, which can further reveal the genetic composition of the individual in question.
