A recessive trait reappears in the 2nd generation. The classic example of this would be Gregor Mendel's pea plant cross. He took 2 pea plants, one short and one tall, cut out some of their reproductive parts so they couldn't self pollinate, and crossed their pollen. However, instead of getting a medium sized plant, he got 4 tall plants. This generation is the first, or F1, generation. Where did the short trait go? Did it simply disappear? Or was it being masked? To find out, he let the F1 generation self-pollinate. Surprisingly, there were 3 tall and 1 short plants in the F2 generation. Although the short trait was recessive, it reappeared in the second generation.

Which type of genetic trait appears in every generation of offspring?
A dominant genetic trait appears in every generation of offspring because only one copy of the dominant allele is needed for the trait to be expressed.
What is the ratio of dominant traits to recessive traits in second generation plants?
In second generation plants, the typical ratio of dominant traits to recessive traits, based on Mendelian genetics, is 3:1. This ratio occurs when two heterozygous parents (both carrying one dominant and one recessive allele) are crossed. The dominant trait appears in approximately 75% of the offspring, while the recessive trait appears in about 25%.
What type of trait reappeared in the second generation?
In genetics, traits that reappear in the second generation are typically referred to as recessive traits. These traits may not be expressed in the first generation (F1) due to the dominance of a different trait but can resurface when the F1 individuals are crossed. This reappearance is a result of the segregation of alleles during gamete formation, allowing the recessive phenotype to manifest in some offspring of the second generation (F2).
When a first generation plant self pollinates what is the ratio of dominate to recessive traits in the second generation plants?
When a first generation plant self pollinates, the ratio of dominant to recessive traits in the second generation plants is typically 3:1. This is based on Mendel's principle of segregation, which predicts that in a monohybrid cross, three plants will exhibit the dominant trait and one will exhibit the recessive trait.
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.
Which type of genetic trait appears in every generation of offspring?
A dominant genetic trait appears in every generation of offspring because only one copy of the dominant allele is needed for the trait to be expressed.
A trait that appears or is expressed in the f1 generation is what?
A trait that appears or is expressed in the F1 generation is considered dominant. Dominant traits will manifest themselves in the offspring when at least one parent carries the dominant allele for that trait.
In mendels experiment a trait that always disappeared in the f1 generation but reappeared in the f2 generation was called the?
recessive trait
Will there be a second generation for the nook?
recessive trait
A trait which always appears when it is present is called what kind of trait?
A trait that always appears when it is present is called an obligate trait. This means that the trait is consistently expressed whenever the underlying genetic or environmental conditions are present.
What is the ratio of dominant traits to recessive traits in second generation plants?
In second generation plants, the typical ratio of dominant traits to recessive traits, based on Mendelian genetics, is 3:1. This ratio occurs when two heterozygous parents (both carrying one dominant and one recessive allele) are crossed. The dominant trait appears in approximately 75% of the offspring, while the recessive trait appears in about 25%.
What did Mendel do in his second law?
The second Mendelian Law is the Law of Segregation. It states that in a cross the parental traits do not merge in the first offspring generation (ie. the recessive, "weaker" trait does not disappear for good) but instead appear unchanged in the second offspring generation. For example, if you cross homozygous dwarf pea plants to homozygous tall, all members of the first offspring generation will be tall. This makes it seem as if the dwarf trait disappears, but it does not. If you inbreed the first offspring generation, you get 25% dwarf plants in the second offspring generation. So the "lost" trait reappears.
What type of trait reappeared in the second generation?
In genetics, traits that reappear in the second generation are typically referred to as recessive traits. These traits may not be expressed in the first generation (F1) due to the dominance of a different trait but can resurface when the F1 individuals are crossed. This reappearance is a result of the segregation of alleles during gamete formation, allowing the recessive phenotype to manifest in some offspring of the second generation (F2).
What kind of trait always appears in the offspring produced in Mendels first experiment?
Dominant
In which generation were recessive traits hidden in all the plants in Mendels experiments?
f2 generation
What is the term for when a trait skips a generation?
The term for when a trait skips a generation is called "recessive inheritance."
The trait that disappeared in the f1 generation?
reappears in some plants in the F2 generation
