How did Mendel find out whether the recessive alleles were still present in the f plants?
he breeded the f1 plants with a recessive homozygous plant and if the offspring (f2) showed the recessive allele, then the recessive allele is still present in the f1 plant
If the alleles for traits in pea plants did not segregate during gamete formation and offspring that were recessive for a trait could be produced only by crossing two plants that where recessive?
Yes.
What happened in mendels experiments when a pea received two different alleles for the same trait?
Unless the alleles are codominate (which Mendel did not have in pea plants), one will be dominate and will be what you see (phenotype) and one will be recessive and you will not see it.
How do dominant and recessive alleles affect pheno type?
An allele can effect the phenotype of an organism by its dominance or recessiveness. If two dominant alleles are crossed the offsprings will carry the dominant trait of the alleles. If a dominant allele is crossed with recessive allele the phenotype of the offsprings will be of that of the dominant allele. And if two recessive alleles are crossed the phenotype of their offsprings will carry the reccesive trait.
According to Mendel what kind of genes disappear in F1 pea plants?
No genes disappear in the F1 generation. Each of the F1 plants was heterozygous, having both dominant and recessive alleles. The recessive phenotype disappears in the F1 generation because all members of that generation carry a dominant allele. In the F2 generation, the recessive phenotype will reappear.
The following seed phenotype a showed up in a generation of plants. Which alleles are recessive?
To determine which alleles are recessive in the seed phenotype, you would need to compare the phenotype of the plants with known dominant phenotypes. Typically, if a phenotype appears in a generation that resembles the parents but differs from the dominant traits, those traits associated with the appearance of phenotype "a" are likely recessive. Observing the inheritance patterns in subsequent generations can further clarify which alleles are recessive based on the phenotypes that re-emerge when homozygous recessive individuals are bred.

Why did the recessive trait appear in the f2 generation mendel?
In Mendel's experiments with pea plants, the recessive trait reappeared in the F2 generation due to the segregation of alleles during gamete formation. When he crossed two heterozygous plants (F1 generation), the alleles for the dominant and recessive traits segregated independently, allowing for the possibility of offspring inheriting two recessive alleles. Consequently, the recessive trait manifested in some of the F2 generation plants when they received one recessive allele from each parent. This demonstrated the principles of inheritance, including the re-emergence of recessive traits after skipping a generation.
What is the meaning for Alleles tt?
In genetics, "tt" represents a homozygous recessive genotype for a specific trait, where both alleles for that trait are recessive. This means that the individual will express the recessive phenotype associated with that trait, as there are no dominant alleles present to mask the effect. For example, if "t" represents a trait for short height in plants, a plant with the genotype "tt" would be short.
How did gregor Mendel become famous?
He discovered dominant and recessive alleles. He also bread and tested 29,000 pea plants
Explain segregation of alleles using pea plants?
if the pea plant has 2 recessive alleles then the plant is gonna come out short.but if it has 1 recessive and one dominant allele then the plant turns out tall, because the dominant allele can be present without the recessive allele.
