- The genotypic ratio of a Mendelian monohybrid cross in the F2 generation is 1:2:1.
- This ratio represents the genetic constitution of offspring: 1 homozygous dominant, 2 heterozygous, and 1 homozygous recessive.
- Gregor Mendel derived this ratio from his experiments with pea plants.
- In this cross, the F1 generation is always heterozygous, while the F2 generation shows segregation of alleles.
Additional Information
- Mendelian Genetics: Mendel's laws of inheritance include the Law of Segregation, which explains the 1:2:1 genotypic ratio in F2 generations.
- Homozygous vs. Heterozygous: Homozygous organisms have identical alleles for a gene (e.g., AA or aa), while heterozygous organisms have different alleles (e.g., Aa).
