The genotype(s) of the Fi generation of pea plants obtained in Mendel'...
Introduction
Mendel’s monohybrid cross experiment focused on the inheritance of a single trait, specifically plant height in pea plants. The two alleles involved were dominant tall (T) and recessive short (t).
Parental Generation (P Generation)
- The parental generation consisted of true-breeding tall plants (TT) and true-breeding short plants (tt).
- The genotype for the tall parent is TT, while the short parent has the genotype tt.
F1 Generation
- The F1 generation results from the cross of the P generation.
- All offspring receive one allele from each parent: T from the tall parent and t from the short parent.
Genotypes of F1 Generation
- The resulting genotype for all F1 plants is Tt.
- Since T is dominant, all F1 plants exhibit the tall phenotype.
Conclusion
- The correct answer regarding the genotype(s) of the F1 generation is (3) Tt only.
- In Mendel's experiment, there are no TT individuals in the F1 generation, as they are produced only from the P generation.
Key Takeaways
- F1 generation comprises Tt only, showcasing dominance of the tall trait.
- The F1 plants are uniform in phenotype but heterozygous in genotype.
This understanding of Mendel's experiments provides essential insights into the principles of inheritance and genetic variation.
