Mendel hypothesized that first-generation plants, when crossed, would display a dominant trait in their offspring. He observed that when he crossed purebred plants with contrasting traits, such as tall and short pea plants, the resulting first-generation (F1) plants exhibited only the dominant trait. This led him to propose the concept of dominance in inheritance, suggesting that some traits mask the expression of others in the presence of a dominant allele.
What else can I help you with?
What was the result of the first gemeration of pea plants that Mendel bred?
The first generation of of pea plants that Mendel bred were tall.
How will the height be expressed in the first- and second-generation plants?
In the first-generation plants, the height may vary due to genetic recombination from the parent plants. In the second-generation plants, the height will tend to show more consistency as the offspring inherit a mix of genetic traits from the first-generation plants, resulting in a more predictable range of heights.
What was the result of the first generation of pea plants that mendel bred?
P generation.
What term did MEndel used to signify his true breeding first gneration?
parental generationparental generation
What is te first generation of offspring in mendels experiments called?
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.

The first generation of of pea plants that Mendel bred were tall.

When plants that are true breeding for different traits of a characteristic are crossed the offspring are called?
first-generation plants
What is te first generation of offspring in mendels experiments called?
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.
Will tall plants always have tall offspring?
no. in the second generation it will have a short offspring , but in the first generation it will have tall offspring
When a first generation plant self pollinates what is the ratio of the dominant to recessive traits in the second generation plants?
1:3
When parent plants are crossed how do scientists refer to the first generation of offspring?
F1
Why were all of mendels first generation plants tall?
All of Mendel's first-generation plants were tall because they were all homozygous dominant for the trait of tallness. This means they received two dominant alleles for tallness from the parental plants, resulting in expression of the tall phenotype.
In which generation were recessive traits hidden in all the plants in Mendels experiments?
f2 generation
What generation were recessive traits visible in a few plants in Mendel experiments?
In Mendel's experiments, recessive traits were visible in the F2 generation. After crossing two purebred plants (P generation), the first filial generation (F1) displayed only the dominant traits. However, when the F1 plants were self-pollinated, the recessive traits reappeared in approximately 25% of the F2 generation.
