In Mendel's experiments, what is the term used to describe the first set of individuals mated in a particular genetic cross?

• A. F1 generation (first filial generation)
• B. Testcross generation
• C. F2 generation (second filial generation)
• D. P generation (parental generation)

Answer: (D)

Verified step by step guidance

1. Understand that in Mendelian genetics, different generations are named to describe their role in genetic crosses.
2. The P generation, or parental generation, refers to the original set of individuals that are mated or crossed at the start of an experiment.
3. The F1 generation (first filial generation) is the offspring resulting directly from the P generation cross.
4. The F2 generation (second filial generation) is the offspring resulting from crossing individuals within the F1 generation.
5. A testcross is a specific type of cross used to determine the genotype of an individual by mating it with a homozygous recessive individual.
