Which of the following best describes a test cross?
Correct Answer: A test cross involves crossing an individual with an unknown genotype with a homozygous recessive individual.
- Step 1: Understand that a test cross is a genetic tool used to determine the genotype of an individual.
- Step 2: Identify the individual with the unknown genotype that you want to test.
- Step 3: Find a homozygous recessive individual. This means this individual has two recessive alleles for a trait.
- Step 4: Cross (mate) the individual with the unknown genotype with the homozygous recessive individual.
- Step 5: Observe the offspring from this cross.
- Step 6: Analyze the traits of the offspring to infer the genotype of the original individual.
