he crossed two pure lines
Recessive traits were visible in the F2 generation of Mendel's experiments, where the offspring of the F1 generation showed a 3:1 ratio of dominant to recessive traits.
The F2 generation showed hidden traits in all plants of Mendel's experiments. This generation resulted from crossing the hybrid F1 generation plants, allowing recessive traits to resurface and become visible in the offspring.
Three times as many shorts plants as tall plants.
Mendel used the term "dominant" to describe a trait that emerged in the F1 generation.
3.1
f2 generation
The F1 generation of crossing a tall plant with a short plant resulted in all tall plants. This is because the tall trait is dominant and the short trait is recessive in Mendel's experiments with pea plants.
True. Gregor Mendel concluded that the tall plants in the P generation passed the factor for tallness to the F1 generation based on his experiments with pea plants and his observations of phenotypic ratios.
Mendel's F1 generation plants showed only one of the two traits present in the parental generation. This indicated that the trait expressed in the F1 generation was dominant, while the other trait was recessive.
The first generation of offspring in Mendel's experiments are called the F1 generation or the first filial generation. These are the offspring resulting from the crossing of two parental or P generation plants.
They differed both in genotype and phenotype. Mendel's F1 generation were all heterozygous Tall. Where his F2 generation had genotype frequencies as follows: 1TT:2Tt:1tt and the phenotype frequency 3tall:1short This is assuming you are referring to his experiments using height as the factor. His other experiments had similar results just replace all the uppercase T's with the dominant allele and the lowercase t's with the recessive trait.
The phenotype of the F1 generation was all tall.
