The F1 (first filial) generation is always 100% heterozygous.
This is because the F1 generation is defined as the offspring of pure-breeding (homozygous) parents carrying different alleles from each other, e.g. AA x aa. All the offspring must be Aa, in other words heterozygous.
AB blood type is always heterozygous because it carries both A and B alleles.
A 1 to 2 to 1 phenotypic ratio in the F2 generation of a monohybrid cross is a sign of incomplete dominance, where the heterozygous genotype results in an intermediate phenotype. This ratio is typical when one allele is not completely dominant over the other, leading to a blended or mixed phenotype in heterozygous individuals.
No, a monohybrid refers to offspring that result from the cross between two individuals that are heterozygous for a single trait (ex: Aa x Aa). It does not specifically refer to the second generation of a self-fertilized plant. The second generation of a self-fertilized plant would generally involve a mix of homozygous and heterozygous individuals for various traits.
In the P generation, one parent is homozygous dominant and the other parent is homozygous recessive. In the F1 generation, the product of a cross between the P generation, the offspring are all heterozygous. In the F2 generation, the product of a cross between the F1 generation, the expected result is 1/4 homozygous dominant, 1/2 heterozygous, and 1/4 homozygous recessive.

All of the F1 generation are heterozygous, therefore 100% exhibit the dominant phenotype. The F2 generation has a ratio of 1 homozygous dominant: 2 heterozygous: 1 homozygous recessive. This results in a phenotypic ratio of 3 dominant: 1 recessive.

If the parent generation consisted of a homozygous dominant parent and a homozygous recessive parent, then the F1 generation would be 100% heterozygous.

Beacause they are dominant and heterozygous and they stay with you even though you may not have the genes
100% heterozygous pea plants. Showing the dominant trait
That is the correct spelling of "heterozygous" (having variant alleles).
