What phenotypic ratio did Mendel consistently observe in the F2 generation of a monohybrid cross?
Understand the Problem
The question is asking about the phenotypic ratio observed by Mendel in the F2 generation of a monohybrid cross. A monohybrid cross involves tracking a single trait. The F2 generation is the result of self-crossing the F1 generation.
Answer
Mendel observed a 3:1 phenotypic ratio in the F2 generation of a monohybrid cross.
In the F2 generation of a monohybrid cross, Mendel consistently observed a phenotypic ratio of 3:1, where three plants exhibit the dominant phenotype for every one plant exhibiting the recessive phenotype.
Answer for screen readers
In the F2 generation of a monohybrid cross, Mendel consistently observed a phenotypic ratio of 3:1, where three plants exhibit the dominant phenotype for every one plant exhibiting the recessive phenotype.
More Information
A monohybrid cross involves tracking the inheritance patterns of a single trait. The F2 generation is the result of self-pollinating the F1 generation, which are the offspring of the initial cross.
Tips
A common mistake is confusing the phenotypic ratio with the genotypic ratio (1:2:1). The phenotypic ratio focuses on observable traits, while the genotypic ratio looks at the combination of alleles.
