Understanding Monohybrid Crosses
In genetics, a monohybrid cross involves studying the inheritance of a single trait. The classic example is the pea plant experiments conducted by Gregor Mendel.
F1 Generation
In a typical monohybrid cross, two homozygous parents are crossed. For instance, if we cross a tall pea plant (TT) with a short one (tt):
- All offspring (F1) will be heterozygous (Tt) and exhibit the dominant trait (tall).
F2 Generation Creation
When these F1 plants (Tt) are self-fertilized, the next generation (F2) is produced:
- Tt x Tt
Possible Gametes
Each parent can produce two types of gametes:
- T (dominant allele)
- t (recessive allele)
Genotypic Combinations
When we combine these gametes, we can form a Punnett square:
- TT (homozygous dominant)
- Tt (heterozygous)
- Tt (heterozygous)
- tt (homozygous recessive)
Genotypic Ratio
The resulting genotypic ratio from the Punnett square is:
- 1 TT: 2 Tt: 1 tt
This means for every four offspring, one will be homozygous dominant, two will be heterozygous, and one will be homozygous recessive.
Conclusion
Thus, the correct answer for the genotypic ratio of the F2 generation in a monohybrid cross is 1:2:1, which is option 'C'.
This ratio highlights the predictable patterns of inheritance that Mendel discovered through his meticulous experiments.
