In genetics, the F2 generation typically exhibits a mix of traits inherited from both parental (P) and first filial (F1) generations. The specific trait that dominates in the F2 generation depends on the inheritance pattern of the traits being studied, such as dominant or recessive alleles. For example, in a classic Mendelian cross, if one trait is dominant, it will appear more frequently in the F2 generation, while recessive traits may re-emerge in a ratio of approximately 3:1. Thus, the dominant trait is often the most observable characteristic in the F2 generation.

When Mendel crossed the offspring generation with another was the trait for shortness lost?
When Mendel crossed the offspring generation, specifically the F1 generation (which displayed the dominant trait), with each other, the trait for shortness (the recessive trait) reappeared in the F2 generation. This occurred in a predictable ratio, typically 3:1, where three plants exhibited the dominant trait and one exhibited the recessive trait. Thus, the trait for shortness was not lost; it remained hidden in the F1 generation but became visible once again in the F2 generation.
Why did traits show up in the f2 generation that were not present in the f1 generation in Mendel27s experiment?
Traits that were masked in the F1 generation reappeared in the F2 generation due to Mendel's law of segregation. During gamete formation, alleles segregate randomly so that each gamete carries only one allele for each trait. When F1 hybrids are crossed, the recessive allele can be passed down and result in the expression of the trait in the F2 generation.
In Mendel's experiment why did wrinkled seeeds show up in the F2 generation even though they were not present in the F1 generation?
Because it's used to show up in only The F2 generation
What is the phenotype in the F1 generation that disappears in a one trait test cross?
The recessive trait phenotype disappears in a one-trait test cross in the F1 generation. This phenotype can reappear in the F2 generation.
How many individuals would be expected to show that a trait in a F2 generation consisting of 80 individuals?
In a F2 generation of 80 individuals, you would expect about 3 individuals to show a trait that follows a typical Mendelian inheritance pattern with a 3:1 ratio in the offspring generation. This is based on the expected ratio of 1:2:1 for a heterozygous cross.
In mendels experiment a trait that always disappeared in the f1 generation but reappeared in the f2 generation was called the?
recessive trait
The trait that disappeared in the f1 generation?
reappears in some plants in the F2 generation
If the F2 generation expressed a trait in a 3.1 ratio the F1 generation MUST be heterozyous for that trait?
True
In which generation were recessive traits hidden in all the plants in Mendels experiments?
f2 generation
What can be expected for the recessive trait of monohybrids from the F2 generation?
In the F2 generation of monohybrids, the recessive trait can reappear in a ratio of 3:1 along with the dominant trait. This is because recessive traits can be masked in the F1 generation but resurface in the F2 generation due to genetic segregation.
What can be expected for the recessive trait of monohybrid from the f2 generation?

What percentage of offspring in the F2 generation displayed the recessive trait?
50% because it divided half to

What was the radio of dominant to recessive phenotype in the F2 generation of Mendel's experiment?
The ratio of dominant to recessive phenotype in the F2 generation of Mendel's experiment was 3:1. This means that for every 3 individuals expressing the dominant trait, there was 1 individual expressing the recessive trait.
What is the phenotype in the F1 generation that disappears in a one trait test cross?
The recessive trait phenotype disappears in a one-trait test cross in the F1 generation. This phenotype can reappear in the F2 generation.
