Ratio of Homozygous Tall and Heterozygous Short Plants in F2 Generation
Understanding Mendel's Monohybrid Cross:
Mendel's monohybrid cross involves crossing two plants that are heterozygous for a single trait. In this case, let's consider a cross between two tall pea plants, one homozygous dominant (TT) and the other heterozygous (Tt) for plant height.
Genotypic Ratio in F1 Generation:
- In the F1 generation, all plants will be heterozygous (Tt) for the tall trait.
Genotypic Ratio in F2 Generation:
- When the F1 generation plants are allowed to self-pollinate, the genotypic ratio of the offspring will be 1:2:1.
- This ratio represents the genotypes TT (homozygous tall), Tt (heterozygous tall), and tt (homozygous short).
Ratio of Homozygous Tall to Heterozygous Short Plants:
- In the F2 generation, the ratio of homozygous tall (TT) to heterozygous short (tt) plants will be 1:1.
- This means that for every homozygous tall plant, there will be one heterozygous short plant.
Therefore, in Mendel's monohybrid cross involving a homozygous tall and a heterozygous tall plant, the ratio of homozygous tall to heterozygous short plants in the F2 generation will be 1:1.
